Although each pluton has a characteristic isotopic composition, the fact that Pb&nbsp;</span><sup>206</sup><span>/Pb&nbsp;</span><sup>204</sup><span>&nbsp;for the Butte Quartz Monzonite varies by 1.3 percent, compared to a range of about 8.6 percent for the batholith as a whole, suggests that perfect isotopic mixing of the magma was not always attained. Whole rock initial Sr&nbsp;</span><sup>87</sup><span>/Sr&nbsp;</span><sup>88</sup><span>&nbsp;for the entire batholith ranges from 0.705 to 0.710, comparable to ranges for the Sierra Nevada and British Columbia batholiths. Ore leads of the Butte district are isotopically very similar to feldspar leads of the host Butte Quartz Monzonite. This isotopic similarity was interpreted by Murthy and Patterson (1961a) to indicate complete mixing of independently derived feldspar lead and ore lead rather than close genetic relationship. However, detailed study of the only sample in the present investigation, from the Donald pluton, that clearly has mixed leads shows significant differences in lead isotopic composition between megacryst K-feldspar and both the groundmass K-feldspar and plagioclase, indicating that isotopic mixing of leads is not complete, even within a single hand specimen. Spatial relations of isotopic differences among the various plutons strongly suggest that complete mixing of leads of different isotopic composition from the magma did not occur in the Butte Quartz Monzonite nor in any other pluton of the batholith, and that the isotopic similarity between Butte ore and feldspar lead of the host rock indeed stems from a genetic association. Lead and strontium isotope ratios generally behave in a similar way; that is, the more radiogenic the lead in a rock, the more radiogenic the strontium. The source of the lead which could produce the isotope variations observed for the batholith is calculated to have a mean age of about 2,200 m.y., which is compatible with ages of Precambrian crystalline rocks in the region, and an isotopic makeup with U&nbsp;</span><sup>238</sup><span>/pb&nbsp;</span><sup>204</sup><span>&nbsp;&lt;9, Th/U &gt; 4, and Rb/Sr of 0.03-0.09. However, no large volumes of prebatholith rocks exposed in the Boulder batholith region are of the required isotopic composition, which is typical of basaltic-gabbroic or quartz dioritic chemical composition. Models involving complete melting of possible source materials to account for the isotope variations are considered and rejected. Mechanisms involving par.tial melting of lower crustal or upper mantle source material appear to be the most viable in explaining the observed isotopic compositions. Assimilation of upper crustal material (i.e., the Precambrian Belt and pre-Belt rocks, in which the lead and strontium are more radiogenic than in the batholith rocks) may have accompanied partial melting of the lower crust or upper mantle and indeed must have played a major role if the source material had a composition isotopically comparable to that observed for oceanic tholelites (i.e., low Th/U, U&nbsp;</span><sup>238</sup><span>/Pb&nbsp;</span><sup>204</sup><span>&nbsp;and Rb/Sr), but would be relatively unimportant if the source material were sufficiently radiogenic to begin with as might be expected from basalt, gabbro, or quartz diorite compositions 2,200 m.y. old. © 1968 Society of Economic Geologists, Inc.</span></p>","language":"English ","publisher":"Society of Economic Geologists ","doi":"10.2113/gsecongeo.63.8.884","issn":"03610128","usgsCitation":"Doe, B.R., Tilling, R., Hedge, C., and Klepper, M.R., 1968, Lead and strontium isotope studies of the Boulder Batholith, Southwestern Montana: Economic Geology, v. 63, no. 8, p. 884-906, https://doi.org/10.2113/gsecongeo.63.8.884.","productDescription":"23 p.","startPage":"884","endPage":"906","costCenters":[],"links":[{"id":369372,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States ","state":"Montana ","city":"Helena, Deer Lodge, Butte, Boulder ","otherGeospatial":"Boulder Batholith","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -112.01934814453125,\n              46.60982785835103\n            ],\n            [\n              -112.57827758789062,\n              46.5720787149159\n            ],\n            [\n              -112.72247314453124,\n              46.380096460287824\n            ],\n            [\n              -112.7197265625,\n              46.059891147620725\n            ],\n            [\n              -112.50274658203125,\n              46.01603873833416\n            ],\n            [\n              -112.36129760742188,\n              46.21785176740299\n            ],\n            [\n              -112.16903686523436,\n              46.308047059262954\n            ],\n            [\n              -112.02209472656249,\n              46.605110653248275\n            ],\n            [\n              -112.01934814453125,\n              46.60982785835103\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"63","issue":"8","noUsgsAuthors":false,"publicationDate":"1968-12-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Doe, B.

Pseudopunctae are interpreted as seats of ciliate papillae or elongate setal follicles, as adaptation to partial burial in soft substrate. Auricular chambers, marginal ridges, and endospines provided effective protection against ingression of coarse or harmful particles. Productus opuntia Waagen is assigned to Echinauris Muir-Wood &amp; Cooper; its habitat and adaptations are interpreted as similar to those of Marginifera. The stratigraphic position of the bed containing the late Permian guide ammonoid Cyclolobus proves to be lower than hitherto thought, thus extending the ammonoid's range.

Predators were removed from the west side of the Refuge while the east side served as a control area. At the end of 3 years, these areas were reversed to reduce the effects of environmental influences. The effect of predator removal was measured by a simulated nest study to determine predation pressure, a check of natural nest success, and weekly breeding pair and brood counts. Results indicated that 60 percent more Class I ducklings were produced on the units where predator control was conducted. Until more is known, reduction of predators to increase waterfowl nesting success should be limited to intensively managed production areas where substantial nest losses are demonstrated.","language":"English","publisher":"Wiley","doi":"10.2307/3799541","usgsCitation":"Balser, D.S., Dill, H.H., and Nelson, H., 1968, Effect of predator reduction on waterfowl nesting success: Journal of Wildlife Management, v. 32, no. 4, p. 669-682, https://doi.org/10.2307/3799541.","productDescription":"14 p.","startPage":"669","endPage":"682","costCenters":[],"links":[{"id":133748,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.er.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Minnesota","otherGeospatial":"Agassiz National Wildlife Refuge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -96.08062071899535,\n              48.441308663632356\n            ],\n            [\n              -96.08062071899535,\n              48.20707610545438\n            ],\n            [\n              -95.76928748057993,\n              48.20707610545438\n            ],\n            [\n              -95.76928748057993,\n              48.441308663632356\n            ],\n            [\n              -96.08062071899535,\n              48.441308663632356\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"32","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4be4b07f02db625327","contributors":{"authors":[{"text":"Balser, D.

Optical, density, single-crystal and powder X-ray diffraction, and major and minor element chemical data are reported.The compositions of the hornblendes show only limited correlation with the chemistry of the rocks in which they occurred. Hornblendes from granitic rocks of the eastern Sierra Nevada and Inyo Mountains have a wide range of tetrahedral aluminum content which is often as low as three-quarters of an atom per formula unit, whereas hornblendes from younger granitic rocks elsewhere in the Sierra Nevada batholith contain more than one atom of tetrahedral aluminum per formula unit. Because an increase of aluminum in tetrahedral co-ordination is considered indicative of higher temperatures of crystallization, the observed differences in the hornblendes suggest that older plutonic rocks of the batholith may have been metamorphosed regionally or may have been affected by widespread hydrothermal action prior to consolidation of later granitic rocks.</span></p>","language":"English","publisher":"Oxford University Press","doi":"10.1093/petrology/9.3.378","usgsCitation":"Dodge, F.C., Papike, J.J., and Mays, R.E., 1968, Hornblendes from granitic rocks of the central Sierra Nevada batholith, California: Journal of Petrology, v. 9, no. 3, p. 378-410, https://doi.org/10.1093/petrology/9.3.378.","productDescription":"33 p.","startPage":"378","endPage":"410","costCenters":[],"links":[{"id":373142,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Central Sierra Nevada Batholith","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -120.08605957031249,\n              36.28413532741724\n            ],\n            [\n              -117.80639648437499,\n              36.28413532741724\n            ],\n            [\n              -117.80639648437499,\n              37.75768707689704\n            ],\n            [\n              -120.08605957031249,\n              37.75768707689704\n            ],\n            [\n              -120.08605957031249,\n              36.28413532741724\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"9","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Dodge, F.
