Experimental drill hole logging in potash deposits of the Carlsbad district, New Mexico
C.L. Jones, C. Gilbert Bowles, Kenneth Granville Bell
1960, Open-File Report 60-84
Experimental logging of holes drilled through potash deposits in the Carlsbad district, southeastern New Mexico, demonstrate the considerable utility of gamma-ray, neutron, and electrical resistivity logging in the search for and identification of mineable deposits of sylvite and langbeinite. Such deposits are strongly radioactive with both gamma-ray and neutron well...
Petrography and petrology of Smoky Butte intrusives, Garfield County, Montana
Robert E. Matson
1960, Open-File Report 60-96
The Smoky Butte intrusives are located in T. 18 N., R. 36 E. Garfield County, Montana on the extreme eastern edge of the petrographic province of Central Montana. They consist of dikes and plugs arranged in linear, en-echelon pattern with a northeast trend and intrude the Tullock member (Paleocene age)...
Origin and chemical composition of evaporite deposits
George William Moore
1960, Open-File Report 60-99
A comparative study of marine evaporite deposits forming at the present time along the pacific coast of central Mexico and evaporite formations of Permian age in West Texas Basin was made in order to determine if the modern sediments provide a basis for understanding environmental conditions that existed during deposition...
Pumice and pozzolan deposits in the Lesser Antilles
Edwin Butt Eckel
1960, Open-File Report 60-48
Early in 1959 the International Cooperation Administration requested the U. S. Geological Survey to assign a geologist to a reconnaissance study of the pumice and pozzolan deposits of the Lesser Antilles. As a result, I made brief field examinations of all the reported deposits during the period May 25 -...
An aeromagnetic reconnaissance of the Cook Inlet area, Alaska
Arthur Grantz, Isidore Zietz, Gordon E. Andreasen
1960, Open-File Report 60-59
Forty-two east-west aeromagnetic lines were flown across the Cook Inlet-Susitna Lowland between Chelatna Lake and Seldovia at a flight altitude of approximately 2,500 feet. The lines traverse all or part of five Mesozoic tectonic elements that dominate the structure of the Cook Inlet area. Each of these tectonic elements, the...
Petrography of the Upper Cambrian dolomites of Warren County, New Jersey
Valentine E. Zadnik
1960, Open-File Report 60-162
Petrographic investigation of the Upper Cambrian dolomites along the Delaware River in Warren County, New Jersey, has led to the distinction of six different microfacies each representing a specific sedimentary environment. In order of decreasing relative depth these microfacies are: dololutite, dolarenite, oolitic dolarenite, dolorudite, cryptozoan dolomite and desiccation dolorudite....
Geology and ore deposits of the Klondike Ridge area, Colorado
John David Vogel
1960, Open-File Report 60-145
The region described in this report is in the northeastern part of the Colorado Plateau and is transitional between two major structural elements. The western part is typical of the salt anticline region of the Plateau, but the eastern part has features which reflect movements in the nearby San Juan...
Geology of the Jackson Mountains, Humbolt County, Nevada
Charles Ronald Willden
1960, Open-File Report 60-155
The Jackson Mountains, a prominent range near the center of Humboldt County, Nevada, are of interest because the Cretaceous rocks in the range record the effects of a late Cretaceous to early Tertiary orogeny. Such an orogeny has been assumed to have effected all of the Great Basin, but the...
