The females were also marked with numbered nasal saddles. Liberation was by the gentle release method, and no special effort was made to isolate or condition the ducklings prior to release. Ducklings were placed in an enclosed pond area at 25 to 45 days of age. Altogether, 627 (97 percent) ducklings reached flight age and dispersed gradually into the wild. All had left the release area by 25 November. First-year band recovery reports indicated that 68 (11 percent) of the birds were shot in 15 states. Their migration pattern was similar to that for immature wild mallards banded in North Dakota in 1970.</p><p>Eighty-nine (33 percent) of a possible 270 marked females returned to Arrowwood Refuge during 1971. When consideration is given to assumed normal natural mortality and crippling loss, an estimated minimum of 43 percent of the surviving females returned to the release area. Returning birds not observed would raise this figure even higher. This potential homing rate is considerably higher than rates reported for other studies using various strains of mallards.

All specimens had Curie temperatures above 500°C, and those from four of the flows had lower Curie temperatures as well, indicating they probably underwent varying degrees of high-temperature oxidation and disproportionation during initial cooling. These four suffered irreversible changes in their blocking temperature spectra when heated in air above 400 to 500°C. Nonetheless, the paleointensities derived by the Thelliers' method below these temperatures agree with the actual values within the uncertainties. The values obtained by the other methods are not as accurate or reliable. In four out of five lavas, A.

There is some evidence that Waianae Volcano was still active when Koolau Volcano emerged from the sea. The predominantly tholeiitic lower and middle members of the Waianae Volcanic Series are approximately contemporaneous and were extruded during the late Gilbert and early Gauss geomagnetic polarity epochs. They were followed within less than 0.2 m.y. by the alkalic lavas of the upper member, which were probably extruded largely during the later part of the Gauss normal polarity epoch. The Koolau Volcanic Series was extruded entirely during the early Matuyama reversed polarity epoch. Data from three thick stratigraphic sections in the Waianae and Koolau Volcanic Series indicate that stacks of lava flows as much as 470 m thick can be formed in less than 0.25 m.y. and that the maximum average period between superimposed lava flows is on the order of 103 yrs. Additional data on the hawaiite flow that led to the discovery of the Kaena reversed event indicate that this reversed flow is 2.85 ± 0.05 m.y. old. Angular dispersion of virtual geomagnetic poles (VGP) in the Hawaiian Islands appears to have decreased during the past 5 m.y. This may be caused by a decrease in dipole wobble, a decrease in the nondipole component of the Earth' magnetic field, or the accumulated effects of weathering, tectonism, and geomorphic processes in older rocks. The mean Waianae and Koolau VGPs are slightly on the side of the Earth's rotation axis away from Oahu. This supports, but does not prove, the hypothesis that the axial dipole is displaced slightly northward from the Earth's center. Three VGP “excursions” were recorded in sections of lava in the Waianae and Koolau ranges. During these excursions, the VGPs appear to have traveled away from or toward the geographic axis along great circle paths, suggesting they may be related to the dipole rather than the nondipole field and may record aborted reversals in polarity or rapid and infrequent dipole tilts.</span></p>","language":"English","publisher":"Geological Society of

Rocks of this composition have not been reported previously, in the Klamath Mountains or elsewhere, but in northwestern Trinity County they make up a large part of the western Paleozoic and Triassic belt. The remainder of the belt consists of northerly trending sinuous zones of two other principal lithologies: radiolarian chert, rhythmically interbedded with slate or phyllite, crops out in three zones in the eastern, central, and western parts of the area; and massive metabasalt and metadiabase intruded by gabbro and serpentinite occur in a zone about 3 mi wide in the eastern part of the area.</p><p>Although the predominance of chert fragments makes the chert-argillite breccia apparently unique, rocks that are generally similar, consisting of angular to subangular clasts in a pelitic matrix, have been studied in many localities. Field relations and petrographic features of the chert-argillite breccia—specifically the angularity of clasts, absence of a sandy matrix, preservation of Radiolaria in both chert clasts and pelitic matrix, presence of contorted flow laminae in the matrix, large size of some of the exotic blocks, close association with chert, pillow lava, and limestone, absence of stretching or slickensiding of clasts, and overall dimensions of the unit measurable in miles—variously preclude origin of the rock as a normal sedimentary conglomerate, a tectonic breccia, a tillite, or a subaerial mudflow, but include features common to numerous submarine-slide deposits. We interpret the chert-argillite breccia as the result of uplift and subsequent sliding of a thick deposit of inter-layered chert and pelitic ooze. Brittle fracturing of the chert and mobilization of water-saturated ooze produced the observed features.</p><p>Fossiliferous limestone blocks within the slide-breccia indicate that it is no older than Silurian or Devonian, and it predates Jurassic metamorphism and plutonism. The relation of the breccia to a major northwest-trending fault zone, and to serpentinite within this zone, suggests that the formation of the breccia was generally synchronous with the faulting and ultramafic intrusion. Rocks of the central metamorphic belt, east of the mapped area, were metamorphosed during a Devonian orogeny, and we suggest that the submarine slide-breccia was formed as a frontal effect of the same orogeny.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1973)84<1423:SCSOPA>2.0.CO;2","usgsCitation":"Cox, D.P., and Pratt, W.P., 1973, Submarine chert-argillite slide-breccia of Paleozoic age in the southern Klamath Mountains, California: Geological Society of America Bulletin, v. 84, no. 4, p. 1423-1438, https://doi.org/10.1130/0016-7606(1973)84<1423:SCSOPA>2.0.CO;2.","productDescription":"15 p.","startPage":"1423","endPage":"1438","costCenters":[],"links":[{"id":414550,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Klamath Mountains","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -124.4226593323977,\n              40.37035877012454\n            ],\n            [\n              -122.60770111985475,\n              40.32153750426667\n            ],\n            [\n              -122.35147172514274,\n              40.581509069642124\n            ],\n            [\n              -122.35147172514274,\n              40.888917981387124\n            ],\n            [\n              -122.27673815168488,\n              41.194905355525776\n            ],\n            [\n              -122.47958642249858,\n              41.70703350143842\n            ],\n            [\n              -122.372824174702,\n              42.017127535348635\n            ],\n            [\n              -124.26251596070249,\n              42.00919519536757\n            ],\n            [\n              -124.29454463504153,\n              41.75483814519038\n            ],\n            [\n              -124.08102013944837,\n              41.395436560564406\n            ],\n            [\n              -124.23048728636347,\n              41.178836231809925\n            ],\n            [\n              -124.18778238724494,\n              40.888917981387124\n            ],\n            [\n              -124.48671668107546,\n              40.50037600357953\n            ],\n            [\n              -124.4226593323977,\n              40.37035877012454\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"84","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Cox, Dennis P. dcox@usgs.gov","contributorId":2766,"corporation":false,"usgs":true,"family":"Cox","given":"Dennis","email":"dcox@usgs.gov","middleInitial":"P.","affiliations":[],"preferred":true,"id":867133,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pratt, Walden P.","contributorId":88342,"corporation":false,"usgs":true,"family":"Pratt","given":"Walden","email":"","middleInitial":"P.","affiliations":[],"preferred":true,"id":867134,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Many have a copropelic microstructure and contain labial plates and skin fragments of chironomid larvae. Microfossils of some of these oil shale beds include such normally perishable things as first instar midge larvae, a single spiral chloroplast of a green alga, and sporangia of aquatic fungi. Taken together, these features indicate that the oil shale originated from algal ooze that formed on the bottom of very shallow, spring-fed lakes. The algae (dominantly blue-greens) were not planktonic but grew on, and in, the flocculent ooze. At intervals, perhaps tens to hundreds of years, the lake levels fell enough to expose the algal ooze to the air and partial drying.

Fluorite occurs as a primary mineral in phases of the composite sodic granite stock at Jamestown and in breccia zones, stockworks, and pipe-shaped bodies in and adjacent to the stock. Gold and telluride mineralization occurs with and without fluorite in veins peripheral to the stock. A great variety of fluid-inclusion types is present in the district, reflecting chemically and physically diverse fluids. Fluid inclusions in early-stage quartz from the fluorspar deposits have filling temperatures of 250 degrees to 375 degrees C, salinities of 20 to 30%, and boiling is indicated at many locations. Most inclusions associated with the main fluorite stage have salinities of at least 26% to more than 50% and filling temperatures in the range of 250 degrees to 350 degrees C. Probable cognate fluorite on the inclusion walls and as many as ten daughter minerals precipitated from some primary inclusions in fluorite attest to the presence of salt and CaF&nbsp;</span><sub>2</sub><span>&nbsp;-rich polycomponent fluorspar-depositing fluids. Carbon dioxide-rich liquids and vapors were present during and after the main period of fluorspar deposition.</span></p><p><span>Gold-bearing veins contain fluid inclusions indicating that two fundamentally different types of fluids were present. Inclusions in pregold quartz and fluorite have filling temperatures which range up to 375 degrees C, and most have very high salinities comparable to those from the fluorspar deposits, suggesting that early quartz and fluorite of the gold-bearing veins was roughly contemporaneous with the main period of fluorspar deposition. Fluid inclusion and other thermometric data (Kelly and Goddard, 1969) suggest that gold and telluride deposition occurred at temperatures below 300 degrees C. Fluid inclusions most directly associated with gold deposition have filling temperatures in the range 205 degrees to 270 degrees C and have about 4% salinity. These data suggest that the gold-bearing fluids either evolved from the fluorite-bearing fluids or were later unrelated hydrothermal pulses introduced on reopened structures.</span></p><p><span>Boiling occurred at many locations that were at relatively high elevations or adjacent to the sodic granite stock. From the interpretation that boiling occurred and from the heterogeneity of CO&nbsp;</span><sub>2</sub><span>&nbsp;contents, we deduce that fluid pressures were low and variable, commonly near 150 bars, but ranging to as much as approximately 500 bars when CO&nbsp;</span><sub>2</sub><span>&nbsp;pressures were high; these determinations are compatible with the depth of cover estimated from geomorphic reconstruction using the Flattop peneplain. The absence of strong thermal or salinity zonation of fluids relative to the outcropping stock suggests that fluids were emanating from a larger intrusive body at depth.</span></p>","language":"English","publisher":"GeoScienceWorld","doi":"10.2113/gsecongeo.68.8.1247","usgsCitation":"Nash, J.T., and Cunningham, C.G., 1973, Fluid-inclusion studies of the fluorspar and gold deposits, Jamestown district, Colorado: Economic Geology, v. 68, no. 8, p. 1247-1262, https://doi.org/10.2113/gsecongeo.68.8.1247.","productDescription":"16 p.","startPage":"1247","endPage":"1262","costCenters":[],"links":[{"id":372903,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","otherGeospatial":"Jamestown district","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -105.44746398925781,\n              40.06913905733146\n            ],\n            [\n              -105.32936096191406,\n              40.06913905733146\n            ],\n            [\n              -105.32936096191406,\n              40.14948820651523\n            ],\n            [\n              -105.44746398925781,\n              40.14948820651523\n            ],\n            [\n              -105.44746398925781,\n              40.06913905733146\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"68","issue":"8","noUsgsAuthors":false,"publicationDate":"1973-12-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Nash, J.

Fissure filling and replacement Pb-Zn-Cu-Ag-Au mineralization occurs in both sedimentary and intrusive host rocks over a known vertical distance of 3,000 feet. The paragenesis of three major recognized veins in the mine is nearly the same, consisting of early quartz, anhydrite, hematite, and pyrite + or - chalcopyrite, followed by sphalerite and galena, grading into pyrite + chalcopyrite + hematite, in turn followed by quartz + carbonate and minor anhydrite, followed by sphalerite and chalcopyrite. Deep, early veins outside of the Mayflower ore zone are characterized by quartz, K-feldspar, biotite, pyrite, and anhydrite, and some also contain magnetite, amphibole or chalcopyrite; these veins contain halite-bearing and gas-rich inclusions which are not known from the ore zone. The deep, early fluids had 34 to 44% salinity, homogenization temperatures of 315 degrees to 430 degrees C, and at times were boiling. Fluid inclusions in samples from the three ore-bearing veins, which contain only simple two-phase inclusions with consistent phase proportions, indicate a marked change in the fluids prior to ore deposition. Homogenization temperatures range from 220 degrees to 300 degrees C, and probably require a pressure correction of approximately + 10 degrees C. Freezing tests indicate salinities in the range 0.3 to 11 wt %NaCl equivalent; no CO&nbsp;</span><sub>2</sub><span>&nbsp;-bearing phases were detected at reduced temperatures. Near-surface veins, presumably contemporaneous with the Mayflower ore zone, show evidence for boiling and suggest that there was approximately 90 bars pressure at the present Mayflower vein outcrop. The distribution of fluid densities, temperatures, boiling, and key minerals in time and space indicates a dramatic change from very hot dense post-magmatic fluids to cooler, relatively low salinity fluids at the onset of economic basemetal deposition, probably concurrent with normal faulting. The changes in the physical properties of the hydrothermal fluids are believed to reflect the structural and magmatic evolution of the area.</span></p>","language":"English","publisher":"GeoScienceWorld","doi":"10.2113/gsecongeo.68.1.34","usgsCitation":"Nash, J.T., 1973, Geochemical studies in the Park City district; I, ore fluids in the Mayflower mine : Economic Geology, v. 68, no. 1, p. 34-51, https://doi.org/10.2113/gsecongeo.68.1.34.","productDescription":"18 p.","startPage":"34","endPage":"51","costCenters":[],"links":[{"id":372899,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Utah","otherGeospatial":"Mayflower mine","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.59500122070312,\n              40.52319489128985\n            ],\n            [\n              -111.28326416015625,\n              40.52319489128985\n            ],\n            [\n              -111.28326416015625,\n              40.763901280945866\n            ],\n            [\n              -111.59500122070312,\n              40.763901280945866\n            ],\n            [\n              -111.59500122070312,\n              40.52319489128985\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"68","issue":"1","noUsgsAuthors":false,"publicationDate":"1973-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Nash, J.

The data are derived from a variety of sources, many of them inadequately documented or preliminary, and are not uncommonly inaccurate or conflicting. In this paper we present tabulations of basement ages and depths from DSDP Legs 5, 8, 9, and 16 in the eastern equatorial Pacific, refer them to the latest biostratigraphic time scale, and document and discuss their error limits. We recommend that in future use of this type of data a similar practice be adopted and that the precise source of data, time scale used, and procedures for determining ages and errors be clearly identified in order to avoid confusion. Based on the data presented here, we also give the relations between basement age, distance from the spreading center, and basement depth. The errors inherent in the data cause these relations to be very general and to have less resolution than ascribed to them by some previous investigators.</span></p>","language":"English","publisher":"GSA","doi":"10.1130/0016-7606(1973)84<2361:BAABDI>2.0.CO;2","usgsCitation":"Van Andel, T.H., and Bukry, D., 1973, Basement ages and basement depths in the eastern equatorial pacific from Deep Sea Drilling Project Legs 5, 8, 9, and 16: GSA Bulletin, v. 84, no. 7, p. 2361-2379, https://doi.org/10.1130/0016-7606(1973)84<2361:BAABDI>2.0.CO;2.","productDescription":"9 p.","startPage":"2361","endPage":"2379","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":372784,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Pacific Ocean","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -125.859375,\n              41.64007838467894\n            ],\n            [\n              -157.32421875,\n              40.3130432088809\n            ],\n            [\n              -156.62109374999997,\n              -1.0546279422758742\n            ],\n            [\n              -90.703125,\n              5.266007882805498\n            ],\n            [\n              -95.80078125,\n              23.241346102386135\n            ],\n            [\n              -125.859375,\n              41.64007838467894\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"84","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Van Andel, T.

Spinel lherzolite xenoliths and megacrysts of augite and andesine have been found in lava flows and cinder deposits. Using analytical data on the rocks and minerals and simple thermodynamic expressions, the pressures and temperatures of equilibration of lavas and xenoliths, megacrysts and phenocrysts have been calculated. The lavas could have been in equilibrium with lherzolite at 1 330–1 410° C and 27.5–31.6 kb, the more silica-poor liquid having the higher values. The basanitoid could have equilibrated with the megacrysts at about 10.5 kb and with phenocrysts at about 1.4 kb and 1130° C. The variation in composition of the lavas may be explained by a rising zone of melting within the mantle, the most silica-poor liquid having the deepest source. The source of the San Quintin basalts is probably related to spreading of the ocean floor in the Gulf of California.</span></p>","language":"English","publisher":"Springer-Verlag","doi":"10.1007/BF00377648","usgsCitation":"Bacon, C.R., 1973, Stages in the P-T path of ascending basalt magma:  an example from San Quintin, Baja California: Contributions to Mineralogy and Petrology, v. 41, no. 1, p. 1-22, https://doi.org/10.1007/BF00377648.","productDescription":"22 p.","startPage":"1","endPage":"22","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":358828,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Mexico","otherGeospatial":"Baja California, San Quintin","volume":"41","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Bacon, Charles R. 0000-0002-2165-5618 cbacon@usgs.gov","orcid":"https://orcid.org/0000-0002-2165-5618","contributorId":2909,"corporation":false,"usgs":true,"family":"Bacon","given":"Charles","email":"cbacon@usgs.gov","middleInitial":"R.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":749832,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
