Continuous equilibrium temperature logs were measured in 12 idle oil wells located within the onshore Ventura Avenue, San Miguelito, Filmore, Oxnard, and West Montalvo fields to an average depth of about 3100 m (10,200 feet). Thermal conductivities were measured on all available samples. Heat flows were calculated with the aid of a thermostratigraphic scheme based on correlative gradient intervals and average thermal conductivity for the appropriate units. Negative curvature of the Ventura Avenue temperature profiles may be explained by an increase in thermal conductivity associated with tectonic compaction of the underlying Pliocene clastic sequence. Temperature profiles at Fillmore are enigmatic but suggest highly unusual geotectonic conditions. Basinwide, heat flow averages about 48 mW/m</span><sup>2</sup><span>, a value which is low relative to most of southern California. As heat flow does not vary systematically to the maximum measured depth of about 4 km, this anomaly is not easily explained in terms of hydrologic effects or recent uplift and erosion.

The Tertiary volcanic rocks of the area can be divided into a sequence of 26- to 24-Ma intermediate lavas, a sequence of 24- to 22-Ma silicic ash-flow tuffs, and a sequence of 20- to 15-Ma intermediate lavas. We classify these rocks as the older, middle, and younger sequences. Sedimentary rocks, and latites and basalts 12 Ma old or younger, locally overlie the younger intermediate lavas south of the mine. Silicified rhyolite tuff in the lower part of the middle tuff sequence is the principal host of the precious metal ore. Most ore occurs under an acid-leached zone of alunitic alteration and is contained in hydrothermal breccias that crosscut early quartz-pyrite and alunite alteration.Field relations and K-Ar ages of hypogene alunite indicate that precious metal mineralization and alunitic and silicic alteration formed at about 19 to 18 Ma, several million years after eruption of the main host rock. Mineralization formed during high-angle faulting related to crustal extension. Low-angle normal faults are present 5 km northeast of the Paradise Peak mine, but they formed more than 2 Ma after formation of the Paradise Peak deposit. Silicic and alunitic alteration and precious metal mineralization are generally absent in areas of low-angle faulting.Regional stratigraphic relations and K-Ar ages indicate that volcanism changed from silicic ash-flow tuffs to intermediate lavas at about 20 to 19 Ma. Regionally extensive angular unconformities indicate that a period of \"pre-Basin and Range\" crustal extension occurred between about 22 to 19 Ma. This extension was penecontemporaneous with the shift in the style of volcanism and with gold-silver mineralization in the Paradise Peak mine and in the Goldfield and Tonopah districts of western Nevada. The close temporal and spatial relationships of precious metal mineralization with pre-Basin and Range extension suggest that extension was a major factor in the genesis of early Miocene precious metal deposits in the western Great Basin.</p></div>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.84.3.631","issn":"03610128","usgsCitation":"John, D., Thomason, R., and McKee, E., 1989, Geology and K-Ar geochronology of the Paradise Peak Mine and the relationship of pre-Basin and Range extension to Early Miocene precious metal mineralization in west-central Nevada: Economic Geology, v. 84, no. 3, p. 631-649, https://doi.org/10.2113/gsecongeo.84.3.631.","productDescription":"19 p.","startPage":"631","endPage":"649","numberOfPages":"19","costCenters":[],"links":[{"id":223086,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"84","issue":"3","noUsgsAuthors":false,"publicationDate":"1989-05-01","publicationStatus":"PW","scienceBaseUri":"505a228fe4b0c8380cd5715f","contributors":{"authors":[{"text":"John, D.

A transient stress peak is produced when the strain rate in the gouge is suddenly increased, whereas a transient stress drop results from a sudden change to a slower strain rate. We have studied the mechanism responsible for these observations by performing frictional sliding experiments on sawcut granite samples filled with a layer of several different fault gouge types. Changes in pore volume and strength were monitored as the sliding velocity alternated between fast and slow rates. Pore volume increased at the faster strain rate, indicating a dilation of the gouge layer, whereas volume decreased at the slower rate indicating compaction. These results verify that gouge dilation is a function of strain rate. Pore volume changed until an equilibrium void ratio of the granular material was reached for a particular rate of strain. Using arguments from soil mechanics, we find that the dense gouge was initially overconsolidated relative to the equilibrium level, whereas the loose gouge was initially underconsolidated relative to this level. Therefore, the transient stress behavior must be due to the overconsolidated state of the gouge at the new rate when the velocity is increased and to the underconsolidated state when the velocity is lowered. Time-dependent compaction was also shown to cause a transient stress response similar to the velocity-dependent behavior. This may be important in natural fault gouges as they become consolidated and stronger with time. In addition, the strain hardening of the gouge during shearing was found to be a function of velocity, rendering it difficult to quantify the change in equilibrium shear stress when velocity is varied under certain conditions.</p></div></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0191-8141(89)90100-4","issn":"01918141","usgsCitation":"Morrow, C., and Byerlee, J., 1989, Experimental studies of compaction and dilatancy during frictional sliding on faults containing gouge: Journal of Structural Geology, v. 11, no. 7, p. 815-825, https://doi.org/10.1016/0191-8141(89)90100-4.","productDescription":"11 p.","startPage":"815","endPage":"825","numberOfPages":"11","costCenters":[],"links":[{"id":223804,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0de2e4b0c8380cd53235","contributors":{"authors":[{"text":"Morrow, C.A.","contributorId":99977,"corporation":false,"usgs":true,"family":"Morrow","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":370206,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Byerlee, J.D.","contributorId":69982,"corporation":false,"usgs":true,"family":"Byerlee","given":"J.D.","affiliations":[],"preferred":false,"id":370205,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Field, petrographic, and rock magnetic evidence indicates that the carrier of this magnetization is detrital, low-Ti titanomagnetite. The detrital titanomagnetite was remagnetized at low temperatures (75°–150°C) probably completely during folding. Anisotropy of magnetic susceptibility and petrographic observations indicate that the detrital titanomagnetite has been affected by tectonic strain. We suggest that low-temperature remagnetization of the detrital titanomagnetite was either a viscous partial thermoremanent magnetization, the acquisition of which was enhanced by stress, or a piezoremanent magnetization that involved stress-induced movement of domain walls during intracrystalline strain, or was a combination of the two mechanisms. Stress may promote remagnetization at temperatures much lower than predicted by current theoretical models. Other mechanisms, such as acquisition of chemical remanent magnetization during folding, deflection of a prefolding magnetization by internal strain, or combination of components of magnetization with different direction cannot account for the geometry of magnetization in the Preuss. The locus of acquisition of synfolding magnetization in the Preuss migrated in conjunction with deformation in the thrust belt. A model is presented in which synfolding magnetization was acquired during cooling and folding as strata moved up thrust ramps. A lack of reverse-polarity directions remains a puzzling feature of the remanence. The remanent direction is tentatively interpreted to reflect the predominant polarity state during its acquisition over an extended rather than a discrete time period during folding in Late Cretaceous and early Tertiary (?) periods of predominantly normal polarity.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB094iB10p13681","issn":"01480227","usgsCitation":"Hudson, M., Reynolds, R.L., and Fishman, N., 1989, Synfolding magnetization in the Jurassic Preuss Sandstone, Wyoming- Idaho-Utah thrust belt: Journal of Geophysical Research Solid Earth, v. 94, no.

The 20-km-long central segment of the 1966 Parkfield rupture, extending from the mainshock epicenter at Middle Mountain southeastward to Gold Hill, forms a 1- to 2-km salient northeastward away from the dominant N40°W strike. Following the 1966 earthquake afterslip, aseismic slip has been nearly constant. Moderate Parkfield earthquakes have recurred on average every 21 years since 1857, when a great earthquake (</span><i>M</i><span>≈8) ruptured at least as far north as the southern Parkfield segment. Many measurements of slip have been made near Parkfield since 1966. Nevertheless, much of the history of surface slip remained uncertain, especially the total amount associated with the 1966 event. In 1985 we measured accumulated slip on the four oldest cultural features offset by the fault along the 1966 Parkfield rupture segment. We interpret net slip on each feature as a sum of event slip (sum of coseismic and rapid preseismic and postseismic slip) from Parkfield earthquakes and steady interseismic slip as measured over the last 20 years on nearby alinement arrays, creep meters, and trilateration lines. We assumed for each site that event slip was identical for the 1922, 1934, and 1966 Parkfield events and that long-term average rate of interseismic slip was constant between all events. Two fences on the southern segment, southeast of Gold Hill, indicate event slip of 13 and 15 cm and interseismic slip rate of 0.36 and 0.30 cm/yr since 1959 and 1908, respectively. At these sites, redundant independent data support our assumption that both event and interseismic slip occur uniformly. On the central segment, near Parkfield, both the 1934 and the 1966 ruptures offset a bridge built in 1932. Interseismic slip rate near the bridge has been about 1.1 cm/yr since 1966; thus we deduce an average event slip of 31 cm for the 1934 and 1966 earthquakes. On a parallel fault trace, 1 km to the southwest, slip was about 8 cm in 1966; thus total event slip summed across the entire fault zone near Parkfield was nearly 40 cm. On Middle Mountain, 4 km north of the 1966 mainshock epicenter, an offset fence indicates 17 cm of slip in 1966 and a 2.26-cm/yr interseismic slip rate since circa 1946. Thus the central segment of the 1966 rupture is characterized by much larger event slip (∼40 cm) than both distal segments (∼15 cm). This amount of surface slip per event is about twice what had been previously assumed. Larger 1966 surface slip in the central part of the rupture is geodetically compatible with a coseismic slip of 65±10 cm slip on a narrow, buried asperity between Middle Mountain and Gold Hill that has been inferred from the depth distribution of early aftershocks. Assuming our characteristic surface slip model, one can further deduce a deficit in slip since the great 1857 earthquake. Taking the long-term slip rate as 3.3 cm/yr, the surface slip deficit is 3±0.2 m south of Gold Hill but only 0.3±0.3 m northward from Parkfield.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB094iB12p17647","issn":"01480227","usgsCitation":"Lienkaemper, J.J., and Prescott, W., 1989, Historic surface slip along the San Andreas Fault near Parkfield, California: Journal of Geophysical Research Solid Earth, v. 94, no.

Survey by 100- and 500-kHz sidescan sonar documents that structural failure of the revetments is not related to lake-bottom undermining. The size and weight of the rock fill in the cribs is identified as a critical factor. Long-term effects of wave surge combined with ice action and gravity can remove rock fill either through breaks in the timber crib wall, or where revetment design offers lakeward exposure of the rock fill. Capstones are displaced when they lose underlying support. Revetments with a lakeward face of steel sheetpile, or toe protection mounded high against the structure, have no significant capstone displacement and are models for improved design. This study supports a rebuilding project that will bury the old revetments with new structures having a lakeward face of either steel sheetpile or a rubble mound.","largerWorkTitle":"Coastal Zone: Proceedings of the Symposium on Coastal and Ocean Management","conferenceTitle":"Coastal Zone '89: Proceedings of the Sixth Symposium on Coastal and Ocean Management","conferenceDate":"11 July 1989 through 14 July 1989","conferenceLocation":"Charleston, SC, USA","language":"English","publisher":"Publ by ASCE","publisherLocation":"New York, NY, United States","usgsCitation":"Chrzastowski, M.J., 1989, Sidescan sonar examination of deteriorated revetments and bulkheads along Chicago's lake front, <i>in</i> Coastal Zone: Proceedings of the Symposium on Coastal and Ocean Management, v. 4, no. pt4, Charleston, SC, USA, 11 July 1989 through 14 July 1989, p. 3931-3944.","startPage":"3931","endPage":"3944","numberOfPages":"14","costCenters":[],"links":[{"id":224366,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","issue":"pt4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8ef5e4b08c986b318c54","contributors":{"authors":[{"text":"Chrzastowski, Michael J.","contributorId":28643,"corporation":false,"usgs":true,"family":"Chrzastowski","given":"Michael","email":"","middleInitial":"J.","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":370738,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

In order to go some way towards remedying this, 1500 km of high-resolution seismic reflection data and 800 km of sidescan sonar imagery have been collected. On the basis of these data and observations made during ten submersible dives, more than 800 bottom samples were collected and evaluated for texture and composition. The understanding of the sedimentary framework of the southern Maine shelf and the processes that maintain it are summarized, and future research directions to evaluate the strategic mineral potential are indicated. In the past 14,000 years, the Maine shelf has experienced a deglaciation and two marine transgressions separated by a regression. The deglaciation was accompanied by the first transgression and deposited till interbedded with up to 40 m of glaciomarine sediment (the Presumpscot Formation) across the shelf. The first transgression culminated about 12,500 yrs B.P., and its landward limit is marked by large glaciomarine deltas 50-100 km landward of the present-day coast. Sea level fell until about 9500 yrs B.P., when shorelines were cut at about the 65 m depth and some large \"lowstand deltas\" were deposited. Sea level has risen since then and in the general absence of modern river sediment input marine processes have reworked the older sediment. Five shelf environments have been defined in terms of their surficial sediment and stratigraphy. Nearshore ramps are sandy regions extending to about 30 m deep offshore of sandy beaches. These may be reworked lowstand deltas, and possess the thickest bodies of sand in the region. Nearshore basins are mud-filled troughs seaward of coastal areas lacking significant river input. Slumping glaciomarine deposits provide most of the Holocene mud that floors these basins. Rocky zones are extensive areas of exposed rock most common in the 30-50 m depth range. These are areas of high carbonate productivity and provide shell fragments to adjacent areas. The outer basins are muddy regions that begin at the 65 m shoreline and extend beyond the 100 m isobath to the deep Gulf of Maine. Finally, shelf valleys are former stream courses that connect nearshore ramps and basins to the outer basins. These bedrock-framed valleys are filled with sand and mud and are apparently still active conduits for the offshore movement of sediment. The mineralogy of the shelf sediment is complex, and it is not yet clear whether glacial homogenization has obliterated distinctions between river drainage basins and the adjacent shelf. Studies are continuing into northern Maine and analysis of the heavy mineralogy of the shelf sediment utilizing a 2 m Humphrey Spiral to process large grab samples and cores has begun. ?? 1989.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00253227","usgsCitation":"Kelley, J.T., Belknap, D.F., and Shipp, R.C., 1989, Sedimentary framework of the southern Maine inner continental shelf: Influence of glaciation and sea-level change: Marine Geology, v. 90, no. 1-2, p. 139-147.","startPage":"139","endPage":"147","numberOfPages":"9","costCenters":[],"links":[{"id":223816,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"90","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8a26e4b08c986b31706b","contributors":{"authors":[{"text":"Kelley, J.

Use of the prediction equation will improve the accuracy of rapid assessments of damage that would be caused by the flood resulting from an embankment dam failure.","conferenceTitle":"Proceedings of the 1989 National Conference on Hydraulic Engineering","conferenceDate":"14 August 1989 through 18 August 1989","conferenceLocation":"New Orleans, LA, USA","language":"English","publisher":"Publ by ASCE","publisherLocation":"New York, NY, United States","isbn":"0872627195","usgsCitation":"Froehlich, D.C., 1989, Peak outflow from a breached embankment dam, Proceedings of the 1989 National Conference on Hydraulic Engineering, New Orleans, LA, USA, 14 August 1989 through 18 August 1989, p. 136-141.","startPage":"136","endPage":"141","numberOfPages":"6","costCenters":[],"links":[{"id":224415,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7610e4b0c8380cd77ed8","contributors":{"authors":[{"text":"Froehlich, David C.","contributorId":58617,"corporation":false,"usgs":true,"family":"Froehlich","given":"David","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":370739,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

More recently, however, inductively coupled plasma mass spectrometry (ICP-MS) has been used to determine Pb-isotope ratios for mineral exploration. The ICP-MS technique, although not as precise as TI-MS, may promote a wider application of Ph-isotope ratio methods because it allows individual isotopes to be determined more rapidly, generally without need for chemical separation (e.g., Smith et al., 1984; Hinners et al., 1987).

For example, simulations incorporating varying levels of matrix sparseness (presence of zeros indicating lack of data) and computation of expected values reveal that not only are all common coefficients influenced by zero data, but also that some coefficients do not discriminate between sparse or dense matrices (few zero data). Such coefficients computationally merge mutually shared and mutually absent information and do not exploit all the information incorporated within the standard 2 ?? 2 contingency table; therefore, the commonly used formulae for such coefficients are more complicated than the actual range of values produced. Other coefficients do differentiate between mutual presences and absences; however, a number of these coefficients do not demonstrate a linear relationship to matrix sparseness. Finally, simulations using nonrandom matrices with known degrees of row-by-row similarities signify that several coefficients either do not display a reasonable range of values or are nonlinear with respect to known relationships within the data. Analyses with nonrandom matrices yield clues as to the utility of certain coefficients for specific applications. For example, coefficients such as Jaccard, Dice, and Baroni-Urbani and Buser are useful if correction of sparseness is desired, whereas the Russell-Rao coefficient is useful when sparseness correction is not desired. ?? 1989 International Association for Mathematical Geology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mathematical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers-Plenum Publishers","doi":"10.1007/BF00893319","issn":"08828121","usgsCitation":"Archer, A., and Maples, C., 1989, Response of selected binomial coefficients to varying degrees of matrix sparseness and to matrices with known data interrelationships: Mathematical Geology, v. 21, no. 7, p. 741-753, https://doi.org/10.1007/BF00893319.","startPage":"741","endPage":"753","numberOfPages":"13","costCenters":[],"links":[{"id":205442,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00893319"},{"id":224090,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaa68e4b0c8380cd862f6","contributors":{"authors":[{"text":"Archer, A.W.","contributorId":8620,"corporation":false,"usgs":true,"family":"Archer","given":"A.W.","affiliations":[],"preferred":false,"id":370840,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Maples, C.G.","contributorId":7425,"corporation":false,"usgs":true,"family":"Maples","given":"C.G.","email":"","affiliations":[],"preferred":false,"id":370839,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
