Slides showing aeromagnetic and gravity data for regional mineral exploration in Colorado, New Mexico, and Arizona
Douglas P. Klein
1983, Open-File Report 83-443
Examples of aeromagnetic and gravity data over 1? x 2? areas are presented for regions near the Cripple Creek mining area, Colorado, and the Lordsburg-Tyrone-Silver City mining areas, southern New Mexico and Arizona. These data indicate broad crustal structures and compositional variations that are marked by magnetization and density contrasts....

Distribution of trace elements in drilling chip samples around a roll-type uranium deposit, San Juan Basin, New Mexico
H.C. Day, C.S. Spirakis, R. S. Zech, A. R. Kirk
1983, Open-File Report 83-56
Chip samples from rotary drilling in the vicinity of a roll-type uranium deposit in the southwestern San Juan Basin were split into a whole-washed fraction, a clay fraction, and a heavy mineral concentrate fraction. Analyses of these fractions determined that cutting samples could be used to identify geochemical halos associated...

Middle and Late Ordovician solitary rugose corals of the Cincinnati Arch region
R.J. Elias
1983, Professional Paper 1066-N
Middle Ordovician (Kirkfieldian) solitary rugose corals have been reported from the Tyrone Limestone of the High Bridge Group and the Curdsville Limestone Member of the Lexington Limestone in central Kentucky. Lambeophyllum? spp. A and B are recognized in the Tyrone Limestone. Grewingkia canadensis (Billings, 1862) and Streptelasma divaricans (Nicholson, 1875b)...

1983, Miscellaneous Field Studies Map 1496-A
In the Chama Basin a wequence of conglomerate, sandstone, and red, gray-green, and pale-purple mudstone occurs stratigraphically between the Upper Jurassic Morrison Formation and Upper Cretaceous Dakota Sandstone. This stratigraphic interval has been called the Burro Canyon Formation by several workers (Craig and others, 1959; Smith and others, 1961; Saucier,...
