A field instrument for quantitative determination of beryllium by activation analysis
William W. Vaughn, E.E. Wilson, J.M. Ohm
1960, Circular 427
A low-cost instrument has been developed for quantitative determinations of beryllium in the field by activation analysis. The instrument makes use of the gamma-neutron reaction between gammas emitted by an artificially radioactive source (Sb124) and beryllium as it occurs in nature. The instrument and power source are mounted in a...

A preliminary report on the copper-cobalt deposits of the Quartzburg district, Grant County, Oregon
John Stewart Vhay
1960, Open-File Report 60-143
The copper- and cobalt-bearing veins of part of the Quartzburg district are in fracture zones trending about N. 70 degrees E. in folded Permian (?) metavolcanic rocks on the southwest side of a quartz diorite stock. Along many of the veins fine-grained tourmaline and quartz have replaced the country rock....
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 damsites on the upper tributaries of the Columbia River in Idaho and Montana - Knowles and Perma damsites, lower Flathead River, Sanders County, Montana
Kenneth S. Soward
1960, Open-File Report 60-128
Knowles and Perma damsites, at river miles 3 and 11 respectively, are alternates for developing the lower Flathead River. A high dam with a flow line at altitude 2,705 feet would back water to Kerr Dam at river mile 72 and would produce a hydraulic head of 235 feet at...

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...
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....
Minor element content of coal from Illinois beds 5 and 6 and their correlatives in Indiana and western Kentucky
Peter Zubovic
1960, Open-File Report 60-165
Spectrographic analyses for 15 elements of 249 block samples of coal are reported here. These samples represent 28 localities of beds 5 and 6 of Illinois and their correlatives in Indiana and western Kentucky.Comparison with the coals of the Northern Great Plains province shows a similarity in the total amount...
