Trace-element distribution around a South Texas roll-type uranium deposit
Charles S. Spirakis
1979, Open-File Report 79-1375
The distribution of trace elements around a south Texas roll-type uranium deposit was examined using semiquantitative emission spectroscopic analytical data complemented by some quantitative data. The results suggest that of the 50 elements analyzed, only beryllium and possibly vanadium are enriched in the altered rock on the updip side of...
Preliminary report on the geology and geophysics of drill hole UE25a-1, Yucca Mountain, Nevada Test Site

Water-quality data from five Oregon stream basins
Timothy L. Miller
1979, Open-File Report 79-1535
The U.S. Geological Survey collected water-quality data in five Oregon stream basins during summer low-flow conditions in 1977 and 1978. During the two sampling periods, a total of 18 different sites were sampled. Several sites were sampled twice in 1977, and some sites were sampled in both 1977 and 1978....
