The Effect Of Dissolution Of Volcanic Glass On The Water Chemistry In A Tuffaceous Aquifer, Rainier Mesa, Nevada, Art F. White, Hans C. Claassen, Larry Benson
The Effect Of Dissolution Of Volcanic Glass On The Water Chemistry In A Tuffaceous Aquifer, Rainier Mesa, Nevada, Art F. White, Hans C. Claassen, Larry Benson
United States Geological Survey: Staff Publications
Geochemistry of ground water associated with the Tertiary tuffs within Rainier Mesa, southern Nevada, was investigated to determine the relative importance of glass dissolution in controlling water chemistry. Water samples were obtained both from interstitial pores in core sections and from free-flowing fractures. Cation compositions showed that calcium and magnesium decreased as a function of depth in the mesa, as sodium increased. The maximum effect occurs within alteration zones containing clinoptilolite and montmorillonite, suggesting these minerals effectively remove bivalent cations from the system.
Comparisons are made between compositions of ground waters found within Rainier Mesa that apparently have not reacted …

Uranium Transport In The Walker River Basin, California And Nevada, Larry Benson, D. L. Leach
Uranium Transport In The Walker River Basin, California And Nevada, Larry Benson, D. L. Leach
United States Geological Survey: Staff Publications
During the summer of 1976 waters from tributaries, rivers, springs and wells were sampled in the Walker River Basin. Snow and sediments from selected sites were also sampled. All samples were analyzed for uranium and other elements. The resulting data provide an understanding of the transport of uranium within a closed hydrologic basin as well as providing a basis for the design of geochemical reconnaissance studies for the Basin and Range Province of the Western United States. Spring and tributary data are useful in locating areas containing anomalous concentrations of uranium. However, agricultural practices obscure the presence of known uranium …

The Mississippian And Pennsylvanian (Carboniferous) Systems In The United States-Nebraska, R. R. Burchett
The Mississippian And Pennsylvanian (Carboniferous) Systems In The United States-Nebraska, R. R. Burchett
Conservation and Survey Division: Faculty and Staff Publications
Nebraska is underlain by rocks of Mississippian and (or) Pennsylvanian age in all but the extreme northeastern part of the State. Only some of the Upper Pennsylvanian strata are exposed; outcrops of these rocks are limited to southeaster Nebraska. This work is published as Conservation and Survey Division GSI-5 and as U.S. Geological Survey PP-1110-P.

During 1978, there were active in Nebraska 33 limestone quarries; 593 sand, gravel and silt or siltstone pits; 7 clay or shale pits; 21 sandstone pits; and 1 peat pit. These 655 mining operations disturbed 892 acres and restored 363 acres during the year. Available as PDF.
