Larvicides are used to control sea lamprey (Petromyzon marinus) in the Great Lakes. These larvicides are useful because they are more toxic to sea lamprey than fish species found in the same habitat. The lampricides come from two classes of chemical compounds: (1) halonitrophenols, and (2) halonitrosalicylanilides. Selectivity of the larvicides appears to be based on the differences in the ability of sea lamprey larvae and fishes to detoxify and/or excrete the chemicals. Glucuronide conjugation is an important mechanism for detoxification of these larvicides by fish, and selectivity of larvicides may be due to differences in glucuronyl transferase activity between lamprey and fishes. If more detailed information were available on uptake, metabolism, excretion, and the biochemistry and physiology of lamprey as compared to fishes, it might be possible to design chemicals that would be more selective than those now in use.

The additional data on kimberlites strengthen our earlier conclusion that kimberlites are derived from a relatively undifferentiated chondritic mantle source. This conclusion is based on the observation that the e{open}Nd values of most of the kimberlites are near zero. In contrast with the kimberlites, their garnet lherzolite inclusions show both time-averaged Nd enrichment and depletion with respect to Sm. Separated clinopyroxenes in eclogite xenoliths from the Roberts Victor kimberlite pipe show both positive and negative e{open}Nd values suggesting different genetic history. A whole rock lower crustal scapolite granulite xenolith from the Matsoku kimberlite pipe shows a negative e{open}Nd value of -4.2, possibly representative of the base of the crust in Lesotho. It appears that all inclusions, mafic and ultramafic, in kimberlites are unrelated to their kimberlite host. The above data and additional Sm-Nd data on xenoliths in alkali basalts, alpine peridotite and alnoite-carbonatites are used to construct a model for the upper 200 km of the earth's mantle - both oceanic and continental. The essential feature of this model is the increasing degree of fertility of the mantle with depth. The kimberlite's source at depths below 200 km in the subcontinental mantle is the most primitive in this model, and this primitive layer is also extended to the suboceanic mantle. However, it is clear from the Nd-isotopic data in the xenoliths of the continental kimberlites that above 200 km the continental mantle is distinctly different from their suboceanic counterpart. ?? 1980 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Contributions to Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF00371888","issn":"00107999","usgsCitation":"Basu, A.R., and Tatsumoto, M., 1980, Nd-isotopes in selected mantle-derived rocks and minerals and their implications for mantle evolution: Contributions to Mineralogy and Petrology, v. 75, no. 1, p. 43-54, https://doi.org/10.1007/BF00371888.","startPage":"43","endPage":"54","numberOfPages":"12","costCenters":[],"links":[{"id":205215,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00371888"},{"id":222252,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"75","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a63c6e4b0c8380cd726ac","contributors":{"authors":[{"text":"Basu, A.

Regression lines fitted to the data yield gradients of 3.8 MPa/km and 6.6 MPa/km for soft and hard rock, respectively. Generally, the maximum shear stress in compressional states of stress for which the least principal stress is oriented near vertically is substantially greater than in extensional stress regimes, with the greatest principal stress in a vertical direction. The equations of equilibrium and compatibility can be used to provide functional constraints on the state of stress. If the stress is assumed to vary only with depth z in a given region, then all nonzero components must have the form A+Bz, where A and B are constants which generally differ for the various components. This implies that the deviatoric stress changes linearly with depth, and the general solution also allows the directions of the horizontal principal stresses to change monotonically with depth. Solutions to the equations, a churning stress to vary with both z and x, were fit to the observations of Zoback and Roller, who measured stress along a horizontal profile near Palmdale, California. The results indicate that the average shear stress in the upper 8 km of the fault zone is about 3.5 MPa less than the shear stress in the far field, but this far field term, which is part of the solution and has the form A+Bz, cannot be evaluated using the existing constant depth data.

Several arguments indicate that the associated seismicity is usually a triggered effect. Among the elements of tectonic state considered here (existing fractures, accumulated elastic strain, and deformational style), deformational style is especially critical in forecasting the occurrence of impoundment-induced seismicity. The observational evidence indicates that seismicity associated with impounding generally occurs in areas that combine steeply dipping faults, relatively high strain rates, and either extensional or horizontal-shear strain. Simple physical arguments suggest: (1) that increased fluid pressures resulting from increased reservoir head should enhance the likelihood of seismic activity, whatever the tectonic environment; (2) that stress changes resulting from surface loading may increase the likelihood of crustal failure in areas of normal and transcurrent faulting, whereas they generally inhibit failure in areas of thrust faulting. Comparisons with other earthquake-producing artificial and natural processes (underground explosions, fluid injection, underground mining, fluid extraction, volcanic emissions) indicate that reservoir loading may similarly modify the natural tectonic state. Subsurface loading resulting from fluid extraction may be a particularly close analogue of reservoir loading; \"seismotectonic\" events associated with fluid extraction have been recognized in both seismically active and otherwise aseismic regions. Because the historic record of seismicity and surface faulting commonly is short in comparison with recurrence intervals of earthquake and fault-slip events, tectonic state is most reliably appraised through combined studies of historic seismicity and faulting, instrumentally measured strain, and the geological record, especially that of the Quaternary. Experience in California and elsewhere demonstrates that the character and activity of recognized faults can be assessed by means of: instrumental earthquake investigations, repeated geodetic measurements, written history, archeological studies, fault topography, and local stratigraphic relations. Where faults are less easily distinguished, appraisals of tectonic state may be based on both the regional seismicity and the regional history of vertical movement as shown by: repeated levelling and sea-level measurements, written history, archeologic investigations, terrace and shoreline deformation, and denudation and sedimentation studies.

Here NMR spectroscopy is used to identify more clearly the chemical structural components of some marine sedimentary fulvic acids, thus enabling a more useful examination of their relationship to more complex humic substances. ?? 1980 Nature Publishing Group.","language":"English","publisher":"Nature","doi":"10.1038/285560a0","issn":"00280836","usgsCitation":"Hatcher, P.G., Breger, I.A., and Mattingly, M., 1980, Structural characteristics of fulvic acids from Continental Shelf sediments: Nature, v. 285, no. 5766, p. 560-562, https://doi.org/10.1038/285560a0.","productDescription":"3 p.","startPage":"560","endPage":"562","numberOfPages":"3","costCenters":[],"links":[{"id":222635,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205274,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/285560a0"}],"volume":"285","issue":"5766","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9bcfe4b08c986b31d0d6","contributors":{"authors":[{"text":"Hatcher, Patrick G.","contributorId":93625,"corporation":false,"usgs":true,"family":"Hatcher","given":"Patrick","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":362686,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Breger, Irving A.","contributorId":65205,"corporation":false,"usgs":true,"family":"Breger","given":"Irving","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":362684,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mattingly, M.A.","contributorId":72262,"corporation":false,"usgs":true,"family":"Mattingly","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":362685,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70170291,"text":"70170291 - 1980 - Eruptions on Mount Etna during 1979","interactions":[],"lastModifiedDate":"2016-04-15T15:56:17","indexId":"70170291","displayToPublicDate":"1980-01-01T00:00:00","publicationYear":"1980","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1435,"text":"Earthquake Information Bulletin (USGS)","active":true,"publicationSubtype":{"id":10}},"title":"Eruptions on Mount Etna during 1979","language":"English","publisher":"U.S Geological Survey","usgsCitation":"Guest, J., Murray, J., Kilburn, C., and Lopes, R., 1980, Eruptions on Mount Etna during 1979: Earthquake Information Bulletin (USGS), v. 12, no. 4, p. 154-160.","productDescription":"7 p.","startPage":"154","endPage":"160","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":320082,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"571210b0e4b0ef3b7ca643dc","contributors":{"authors":[{"text":"Guest, J.","contributorId":168628,"corporation":false,"usgs":false,"family":"Guest","given":"J.","affiliations":[],"preferred":false,"id":626789,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Murray, J.","contributorId":94837,"corporation":false,"usgs":true,"family":"Murray","given":"J.","affiliations":[],"preferred":false,"id":626790,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kilburn, C.","contributorId":149562,"corporation":false,"usgs":false,"family":"Kilburn","given":"C.","email":"","affiliations":[],"preferred":false,"id":626791,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lopes, R.","contributorId":61554,"corporation":false,"usgs":true,"family":"Lopes","given":"R.","affiliations":[],"preferred":false,"id":626792,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":24611,"text":"ofr801172 - 1980 - Seismic hazard study of the western portion of the Garlock fault [California]","interactions":[],"lastModifiedDate":"2025-01-14T21:29:13.607587","indexId":"ofr801172","displayToPublicDate":"1980-01-01T00:00:00","publicationYear":"1980","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"80-1172","title":"Seismic hazard study of the western portion of the Garlock fault [California]","docAbstract":"Investigations of the western segment of the Garlock fault were conducted at Castac Lake, Twin Lakes and Oak Creek Canyon. Studies were concentrated on the youngest fault trace as delineated by Clark (1973). Seismic refraction surveys, topographic surveys and geologic mapping provided positive evidence for fault offsets in Quaternary deposits at Twin Lakes and Oak Creek Canyon.
Investigations at Castac Lake were concentrated on the fault segment north of the lake. Previous investigations south of the lake and across the dry lake bottom exposed unbroken strata dating back 8050 +300 years B.P. No evidence of offset of young deposits was found north of the lake from surface investigations or seismic refraction data.
Trenching of sag pond deposits at Twin Lakes revealed fault traces representing 2 events confined to a zone 3 meters wide. The stratigraphy at Twin Lakes consists of alternating units of clay and sand allowing measurements of vertical offsets. Based on radiocarbon dates of detrital charcoal, the most recent movement occurred less than 890 +195 years B.P. and the proceeding event occurred greater than 2,800 +165 years B.P. Total vertical offset was 80 to 100 cm for the most recent movement and 55-60 cm for the proceeding event.
Geomorphic analysis of offset alluvial stream channels at Oak Creek Canyon provided an estimate of 1.6 to 3.3 mm per year of left lateral movement during Holocene and late Pleistocene times. This estimate is based on correlation of soil profile development with dated soil stratigraphy in the San Joaquin Valley. Scarp heights and lack of definitive evidence for recent left-lateral offset in Oak Creek Canyon indicates a significant and perhaps predominant vertical component of movement with: 1) a comparatively long recurrence interval and/or 2) a small component of left-lateral movement. Arching of late Pleistocene deposits in Oak Creek Canyon is consistent with right-lateral rather than left-lateral wrench faulting, suggesting a fluctuation in stresses along this part of the fault since late Pleistocene time.

Even when the estimate of the refractor velocity is poorly determined, useful estimates of the station time-terms can be made. The method is applied to a 20 km diameter network of eight seismic stations which was operated near Castaic, California, during the winter of 1972-73. The stations were located in sedimentary basins. Beneath the network, the sedimentary rocks of the basins are known to range from 1 to more than 4 km in thickness. Relative time-terms are estimated from P-waves assumed to be propagated by a refractor in the mid-crust, and again from P-waves propagated by a refractor in the upper basement. For the range of velocities reported by others, the two sets of time-terms are very similar. They suggest that both refractors dip to the southwest, and the geology also indicates that the basement dips in this direction. In addition, the P-wave velocity estimated for the refractor of mid-crustal depths, roughly 6.7 km/sec, agrees with values reported by others. Thus, even in this region of complicated geologic structure, the method appears to give realistic results. ?? 1980 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF01593058","issn":"00334553","usgsCitation":"Murdock, J., and Steppe, J., 1980, Crustal parameters estimated from P-waves of earthquakes recorded at a small array: Pure and Applied Geophysics PAGEOPH, v. 118, no. 2, p. 1179-1190, https://doi.org/10.1007/BF01593058.","startPage":"1179","endPage":"1190","numberOfPages":"12","costCenters":[],"links":[{"id":205207,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01593058"},{"id":222152,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"118","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fce1e4b0c8380cd4e4aa","contributors":{"authors":[{"text":"Murdock, J.N.","contributorId":41589,"corporation":false,"usgs":true,"family":"Murdock","given":"J.N.","email":"","affiliations":[],"preferred":false,"id":364015,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Steppe, J.A.","contributorId":22087,"corporation":false,"usgs":true,"family":"Steppe","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":364014,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70012627,"text":"70012627 - 1980 - The composition, structure, and stability of guinier-preston zones in lunar and terrestrial orthopyroxene","interactions":[],"lastModifiedDate":"2012-03-12T17:19:04","indexId":"70012627","displayToPublicDate":"1980-01-01T00:00:00","publicationYear":"1980","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3066,"text":"Physics and Chemistry of Minerals","active":true,"publicationSubtype":{"id":10}},"title":"The composition, structure, and stability of guinier-preston zones in lunar and terrestrial orthopyroxene","docAbstract":"Lunar and terrestrial orthopyroxenes (Mg,Fe,Ca)2Si2O6 contain varying abundances of coherent, Ca-enriched Guinier-Preston (G.P.) zones. G.P. zones 5-6 unit cells thick have been found in one lunar sample whereas all other examples (lunar and terrestrial) are only one unit-cell-thick. Electron diffraction maxima from the larger lunar G.P. zones indicate that d100=18.52 A?? whereas, d100=18.2 A?? for the host. This increase in the a direction corresponds to an increase in calcium content in the G.P. zones over that of the host of ???25 mol% Ca2Si2O6. Diffraction patterns of the hk0 net from an area containing G.P. zones show extra spots (h=2 n+1) not observed in the host orthopyroxene (Pbca), that violate the a-glide of the host. The G.P. zones, therefore, have space group Pbc21 if it is assumed that the c-glide of pyroxene is retained and the space group of the G.P. zone is a subgroup of Pbca. The loss of the a-glide in the G.P. zones results in 4 distinct silica chains and 4 distinct cation sites M1A, M1B, M2A, M2B; by symmetry, equivalent M2A or M2B sites are clustered together in only one-half of the unit cell. As one-fourth of the divalent cations in the G.P. zones are calcium, ordering of Ca on M2A or M2B would produce a zone 9 A?? thick extended parallel to (100) with the composition of Ca(Mg,Fe)Si2O6, but constrained by the host to the structure of orthopyroxene. This zone and the Ca-poor half-unit-cell then constitute an 18 A?? thick G.P. zone. Heating experiments of varying duration indicate that the zones become unstable with respect to the host orthopyroxene at ???950??C for Wo0.6 and ???1,050??C for Wo2.5. The zones are interpreted in terms of the pyroxene subsolidus as a metastable phase having either a solvus relationship with orthopyroxene or originating as a distinct phase. The size, distribution, composition and structure of G.P. zones may be an important indicator of the low-temperature thermal history of orthopyroxene. ?? 1980 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Physics and Chemistry of Minerals","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF00311049","issn":"03421791","usgsCitation":"Nord, G.L., 1980, The composition, structure, and stability of guinier-preston zones in lunar and terrestrial orthopyroxene: Physics and Chemistry of Minerals, v. 6, no. 2, p. 109-128, https://doi.org/10.1007/BF00311049.","startPage":"109","endPage":"128","numberOfPages":"20","costCenters":[],"links":[{"id":205270,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00311049"},{"id":222604,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baa4ee4b08c986b3227c1","contributors":{"authors":[{"text":"Nord, Gordon L.

The relatively minor element, mercury, was used for the test case reported here, but the method has been found applicable to forecasts of resources for other mineral products. Mercury resources available in ore in which the average grade is as low as 0.1% are estimated to be 53 ??106kg (1.5 ??106flasks) for the United States and 1551 ??106kg (45 ??106flasks) for the world; this amount is more than adequate to meet predicted demand to the year 2000. The expectable price of mercury in 1978 dollars at this 0.1% grade is projected to be $58.75 per kg ($2,025 per flask), but at a 10% annual inflation rate, it would be more than $12,000 per flask. To satisfy just the projected U.S. demand for mercury by 2000, the price is calculated to be $48.96 per kg ($1,688 per flask) in 1978 dollars at an average annual grade of 0.12%. ?? 1980 Plenum Publishing Corporation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the International Association for Mathematical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers-Plenum Publishers","doi":"10.1007/BF01028882","issn":"00205958","usgsCitation":"Cargill, S., Root, D.H., and Bailey, E.H., 1980, Resource estimation from historical data: Mercury, a test case: Journal of the International Association for Mathematical Geology, v. 12, no. 5, p. 489-522, https://doi.org/10.1007/BF01028882.","startPage":"489","endPage":"522","numberOfPages":"34","costCenters":[],"links":[{"id":205197,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01028882"},{"id":222090,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa9f1e4b0c8380cd86070","contributors":{"authors":[{"text":"Cargill, S.M.","contributorId":64776,"corporation":false,"usgs":true,"family":"Cargill","given":"S.M.","affiliations":[],"preferred":false,"id":364000,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Root, D.

Geophysical profiling and sampling cruises to the northern part of the ridge, an area of recent and future lease sales for petroleum development, provide a strong data base for interpretation of structural and sedimentary patterns and their relation to potential geologic hazards. The northern part of the ridge is a complexly folded and faulted northwest-trending anticlinorium composed mostly of lower and middle Miocene shale and mudstone. Erosional remnants of upper Miocene and Pliocene rocks unconformably overlie highly folded pre-upper Miocene strata. The major structure of the ridge developed almost continuously from Oligocene or early Miocene time to the end of the Tertiary; many small folds formed between post-late Miocene and pre-late Pleistocene time. Numerous small faults cut the rocks on the ridge top. Faults cut basement rocks on the west side of the ridge along the Ferrelo fault zone. Published data on historical epicenters and evidence of offsets on the seafloor from seismic reflection and side-scan profiles, including limited evidence of possible strike-slip movement along fault traces, indicate that the northern Santa Rosa-Cortes Ridge is tectonically active.
The crest of the ridge was truncated as the result of repeated sea-level fluctuations in the Quaternary. A thin veneer of unconsolidated medium to fine sand, less than 3 m thick, mantles most of the ridge; locally in topographically low areas and on the upper flanks of the ridge, thickness exceeds 20 m. The meager sediment cover, coupled with available evidence of relatively strong currents flowing across the ridge top, indicate that the ridge is an area of nondeposition or winnowing of fine sediments. Modern sediments become thicker and finer-grained from the ridge top to the ridge flanks, suggesting active accretion in those areas. Slumps are present at various depths on the flanks, and it seems probable that the thicker deposits (> 20 m) of modern sediments on the upper flanks will be sites of future slumping.

Using the Stacey Kramers (1975) model for lead isotope evolution, isochron model ages range between 720 m.y. and 420 m.y. Most of the massive sulfide deposits in the region formed before 680 m.y. ago, during evolution of the shield. Vein type mineralization of higher lead content occurred during the Pan African event about 550 m.y. ago and continued through the Najd period of extensive faulting in the shield that ended about 530 m.y. ago. Late post-tectonic metamorphism may have been responsible for vein deposits that have model ages less than 500 m.y. Alternatively some of these younger model ages may be too low due to the mineralizing fluids acquiring radiogenic lead from appreciably older local crustal rocks at the time of ore formation. The low207Pb/204Pb ratios found for the deposits in the main part of the shield and for those in north-eastern Egypt, indicate that the Arabian craton was formed in an oceanic crustal environment during the late Precambrian. Involvement of older, upper-crustal material in the formation of the ore deposits in this part of the shield is precluded by their low207Pb/204Pb and208Pb/204Pb characteristics. In the eastern part of the shield, east of longitude 44??20???E towards the Al Amar-Idsas fault region, lead data are quite different. They exhibit a linear207Pb/204Pb-206Pb/204Pb relationship together with distinctly higher208Pb/204Pb characteristics. These data imply the existence of lower crustal rocks of early Proterozoic age that apparently have underthrust the shield rocks from the east. If most of the samples we have analyzed from this easterly region were mineralized 530 m.y. ago, then the age of the older continental rocks is 2,100??300 m.y. (2??). The presence of upper crustal rocks, possibly also of early Proterozoic age, is indicated by galena data from Hailan in South Yemen and also from near Muscat in Oman. These data are the first to indicate such old continental material in these regions. ?? 1980 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Contributions to Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF01132003","issn":"00107999","usgsCitation":"Stacey, J.S., Doe, B.R., Roberts, R.J., Delevaux, M., and Gramlich, J.W., 1980, A lead isotope study of mineralization in the Saudi Arabian Shield: Contributions to Mineralogy and Petrology, v. 74, no. 2, p. 175-188, https://doi.org/10.1007/BF01132003.","startPage":"175","endPage":"188","numberOfPages":"14","costCenters":[],"links":[{"id":205282,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01132003"},{"id":222657,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"74","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e435e4b0c8380cd464db","contributors":{"authors":[{"text":"Stacey, J.

High-rms slopes predicted for the Tharsis-Memnonia-Amazonis volcanic plains from extremely weak radar returns (low peak radar cross section) are qualitatively confirmed by the Viking image data. Large-scale, curvilinear (but parallel) ridges on lava flows in the Memnonia Fossae region are interpreted as innate flow morphology caused by compressional foldover of moving lava sheets of possible rhyolite-dacite composition. The presence or absence of a recent mantle of fine-grained eolian material on the volcanic surfaces studied was determined by the visibility of fresh impact craters with diameters less than 50 m. Lava flows south and west of Arsia Mons, and within the large region of low thermal inertia centered on Tharsis Montes (H. H. Kieffer et al., 1977, J. Geophys. Res.82, 4249–4291), were found to possess such a recent mantle. At predawn residual temperatures ≥ −10K (south boundary of this low-temperature region), lava flows are shown to have relatively old eolian mantles. Lava flows with surfaces modified by eolian erosion and deposition occur west-northwest of Apollinaris Patera at the border of the cratered equatorial uplands and southern Elysium Planitia. Nearby yardangs, for which radar observations indicate very high-rms slopes, are similar to terrestrial features of similar origin.
