Water resources of Grant and Hot Spring Counties, Arkansas
Henry N. Halberg, Charles T. Bryant, Marion S. Hines
1968, Water Supply Paper 1857
In Grant and Hot Spring Counties the Ouachita, Saline, and Caddo Rivers yield large quantities of soft, good-quality water. Small streams in southeastern Hot Spring County and some of the small streams in the Ouachita Mountains have relatively high base flow; in Grant County small streams yield little water during...
Isotopic analysis of uranium in natural waters by alpha spectrometry
K.W. Edwards
1968, Water Supply Paper 1696-F
A method is described for the determination of U234/U238 activity ratios for uranium present in natural waters. The uranium is coprecipitated from solution with aluminum phosphate, extracted into ethyl acetate, further purified by ion exchange, and finally electroplated on a titanium disc for counting. The individual isotopes are determined by...
Utilization of humus-rich forest soil (mull) in geochemical exploration for gold
Gary C. Curtin, H. W. Lakin, G. J. Neuerburg, A.E. Hubert
1968, Circular 562
Distribution of gold in humus-rich forest soil (mull) reflects the known distribution of gold deposits in bedrock in the Empire district, Colorado. Gold from the bedrock is accumulated by pine and aspen trees and is concentrated in the mull by the decay of organic litter from the trees. Anomalies in...

Garland Bayard Gott, Charles J. Zablocki
1968, Circular 595
Extensive geochemical anomalies are present along the west side of the Sheep Creek Range in Lander County, Nev. Anomalous concentrations of zinc, arsenic, mercury, silver, copper, lead, and to some extent gold, molybdenum, and antimony occur in iron-rich material along fracture planes and in quartz veins in Paleozoic formations.
