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....

M. Dean Kleinkopf, J. C. Cole
1983, Open-File Report 83-371
Interpretations of aeromagnetic and gravity data made in support of geologic mapping clearly outline the near-surface shape of Proterozoic granitic units in the Wadi al Jarir (25/42 C) and Al Jurdhawiyah (25/42 D) 1:100,000-scale quadrangles of the northern part of the Arabian Shield. The aeromagnetic data show marked correlation with...

Reconnaissance geology of the Thaniyah Quadrangle, sheet 20/42 C, Kingdom of Saudi Arabia
Robert C. Greene
1983, Open-File Report 83-448
The Thaniyah quadrangle, sheet 20/42 C, is located in the transition zone between the Hijaz Mountains and the Najd Plateau of southwestern Saudi Arabia between lat 20?00' and 20?30' N., long 42?00' to 42?30' E. The quadrangle is underlain by Precambrian metavolcanic, metasedimentary, plutonic, and dike rocks. Metavolcanic rocks consist...

Strata-bound, silver-bearing iron, lead, and zinc sulfide deposits in Silurian and Ordovician rocks of allochthonous terranes, Nevada and northern Mexico
Keith Brindley Ketner
1983, Open-File Report 83-792
Allochthonous terranes in northern Nevada contain strata-bound sulfide deposits at two horizons in Silurian and Ordovician siliceous sedimentary rocks. The most intensively mineralized horizon and most extensive deposit is at the base of the Silurian. Another less extensive deposit is in the lower Middle Ordovician. Spectrographic analyses of gossan from...
Drainage areas of selected sites on streams in North Carolina
Robert L. Meikle
1983, Open-File Report 83-211
For the past several years, drainage-area data have been determined for approximately 12,400 selected sites on streams in North Carolina. Location information, including distance of nearby towns or other landmarks, latitude and longitude coordinates, county in which the site lies, and the name of the latest topographic maps on which...
Stratigraphic framework and distribution of lignite on Crowleys Ridge, Arkansas
Charles R. Meissner
1983, Open-File Report 83-609
The purpose of this report is to establish a stratigraphic framework of lignite beds and associated strata of Crowleys Ridge, Arkansas. Drill hole data provided by the Arkansas Geological Commission is used in the synthesis and interpretation. Areas containing lignite of potential resource value are also delineated. To illustrate the...
Geology and resources of the Andersonville, Georgia, kaolin and bauxite district
