Geochemical maps of the Southern Massanutten Roadless Area, Page and Rockingham counties, Virginia
Frank G. Lesure, Carl L. Forn
1985, Miscellaneous Field Studies Map 1527-B
The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Southern Massanutten Roadless Area to test for indistinct or unexposed mineral deposits that might be recognized by their geochemical halos. Sixty-two stream-sediment and 52 rock samples were collected from within and near the study area by Lesure, assisted...

Map showing gravel-bearing surficial deposits and basaltic rocks near Trinidad, Las Animas County, Colorado
Glenn R. Scott
1985, Miscellaneous Field Studies Map 1738
This map of the Trinidad area is considered to be a special purpose map, as it shows only gravel-bearing alluvial deposits laid down by streams and a series of stacked lava flows erupted from local volcanoes. Nongravelly surficial deposits and Cretaceous bedrock, which would be on a standard geologic map,...
Stratigraphic framework of the upper Fort Union Formation, TA Hills, Western Powder River basin, Wyoming
Jean N. Weaver, Romeo M. Flores
1985, Miscellaneous Field Studies Map 1779
The purpose of this study is to interpret a relationship between the stratigraphy and the environment of deposition of the upper part of the Fort Union Formation in the TA Hills in the western part of the Powder River Basin, Johnson County, Wyoming. This framework was used to map and...
