Ground-followup studies of the 1977 airborne electromagnetic survey in the Assifar and Mulhal areas, Wadi Bidah district, Kingdom of Saudi Arabia
Vincent J. Flanigan, Hamdy Sadek
1983, Open-File Report 83-367
Parts of four airborne electromagnetic (AEM) anomalies were selected for study in order to determine the cause of high conductivity of Precambrian rocks underlying extensive areas in the southern Wadi Bidah district, Kingdom of Saudi Arabia. In the Assifar area, which contains an ancient mine or prospect having the same...
Water-level records for the northern High Plains of Colorado, 1979-83
Joe L. Blattner, Bruce D. Rasmuson
1983, Open-File Report 83-253
Water-level measurements were made in 638 wells in the winter of 1982-83, in the northern High Plains of Colorado. The water-level measurements for the winter of 1982-83 and for four preceding winters are given in a table, which also contains the location, depth, land-surface elevation and the aquifer for each...
Analytical results for 56 rock, 46 stream-sediment and soil, and 22 panned-concentrate samples from the Welcome Creek Wilderness Study Area, Granite County, Montana
W. L. Campbell, G. K. Lee, J.C. Antweiler, R.T. Hopkins
1983, Open-File Report 83-829
Fifty-six rock, 46 stream-sediment, and 22 panned-concentrate samples were collected from the Welcome Creek Wilderness, Granite County, Montana, during the summers of 1979 and 1980. All samples were analyzed for 31 elements by a six-step semiquantitative emission spectrographic method (Grimes and Marranzino, 1968). All panned concentrate and other selected samples...
Report of the U.S. Geological Survey's analytical evaluation program; standard reference water samples M-82 (major constituents), T-83 (trace constituents), N-8 (nutrients), and P-2 (precipitation snowmelt)
