Mineralogy as a guide for exploration in the Montezuma District, central Colorado
Theodore Botinelly
1979, Open-File Report 79-1177
The Montezuma district of central Colorado is a small base metal-silver mining district containing vein deposits associated with a Tertairy porphyry stock. The distribution of tetrahedrite having large unit-cell edges correlates in part with the distribution of more productive mines and suggests areas favorable for further production. The abundance of...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Clear Creek, Monroe County, Indiana
William G. Wilber, Charles G. Crawford, James G. Peters, Frank P. Girardi
1979, Open-File Report 79-1533
The Indiana State Board of Health is developing a State water-quality management plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Clear Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality...
A slingram survey on the Nevada Test Site: part of an integrated geologic geophysical study of site evaluation for nuclear waste disposal
Vincent J. Flanigan
1979, Open-File Report 79-277
A slingram geophysical survey was made in early 1978 as part of the integrated geologlcal-geophysical study aimed at evaluating the Eleana Formation as a possible repository for nuclear waste. The slingram data were taken over an alluvial fan and pediments along the eastern flank of Syncline Ridge about 45 km...

Major-element geochemistry of the Silent Canyon-Black Mountain peralkaline volcanic centers, northwestern Nevada Test Site: applications to an assessment of renewed volcanism
Bruce M. Crowe, Kenneth A. Sargent
1979, Open-File Report 79-926
The Silent Canyon and Black Mountain volcanic centers are located in the northern part of the Nevada Test Site. The Silent Canyon volcanic center is a buried cauldron complex of Miocene age (13-15 m.y.). Black Mountain volcanic center is an elliptical-shaped cauldron complex of late Miocene age. The lavas and...

North American Paleozoic land snails, with a summary of other Paleozoic nonmarine snails
Alan Solem, Ellis Leon Yochelson
1979, Professional Paper 1072
Land snails from the Paleozoic of North America are known from the coal fields of eastern Canada, from the Dunkard basin west of the Allegheny Mountains, and from the western margin of the Illinois basin. The earliest finds were made about 125 years ago; essentially no new information has been...
