Surface adsorption of Cs137 ions on quartz crystals
Stephen Antkiw, H. Waesche, F. Senftle
1954, Trace Elements Memorandum 862
Adsorption tests were made on four large synthetic and three natural quartz crystals to see if surface defects might be detected by subsequent autoradiography techniques. The adsorbent used was radioactive Cs137 in a solution of Cs 137Cl. Natural quartz crystals adsorbed more cesium than the synthetic crystals. Certain surface defects...
Localization of uranium minerals in channel sediments at the base of the Shinarump conglomerate, Monument Valley, Arizona
I. J. Witkind
1954, Trace Elements Investigations 340
During the summers of 1951 and 1952 the U.S. Geological Survey mapped the geology and uranium deposits in three 15-minute quadrangles on the Navajo Indian Reservation in Apache and Navajo Counties, northeastern Arizona. Exposed sedimentary rocks range in age from the Halgaito tongue of the Cutler formation (Permian) to the Salt Wash...
