Quaternary soils and dust deposition in southern Nevada and California Quaternary soils and dust deposition in southern Nevada and California
Eolian dust constitutes much of the pedogenic material in late Pleistocene and Holocene soils of many arid regions of the world. Comparison of the compositions and influx rates of modern dust with the eolian component of dated soils at 24 sites in southern Nevada and California yields information on (1) the composition and influx rate of dust in late Pleistocene and Holocene soils, (2)

Late quaternary history and uranium isotopic compositions of ground water discharge deposits, Crater Flat, Nevada Late quaternary history and uranium isotopic compositions of ground water discharge deposits, Crater Flat, Nevada
Three carbonate-rich spring deposits are present near the southern end of Crater Flat, NV, approximately 18 km southwest of the potential high-level waste repository at Yucca Mountain. We have analyzed five samples of carbonate-rich material from two of the deposits for U and Th isotopic compositions. Resulting U-series disequilibrium ages indicate that springs were active at 18 ?? 1, 30...

Morphology and genesis of carbonate soils on the Kyle Canyon fan, Nevada, U.S.A. Morphology and genesis of carbonate soils on the Kyle Canyon fan, Nevada, U.S.A.
The physical and chemical properties of soils formed in an arid climate on calcareous alluvium of the Kyle Canyon alluvial fan, southern Nevada, were studied in order to infer the rates and relative importance of various soil-forming processes. These studies included field and microscopic observations and analyses of thin sections, major oxides, extractable iron, and clay minerals. The...

Calcic, gypsic, and siliceous soil chronosequences in arid and semiarid environments Calcic, gypsic, and siliceous soil chronosequences in arid and semiarid environments
We studied three soil chronosequences in the western USA to compare the development of calcic, gypsic, and siliceous soils through time. We compared calcic soils from the Silver Lake playa, southeastern California, gypsic-calcic soils from the Kane Fans in Big Horn County, Wyoming, and siliceous-calcic soils from Forty-mile Wash in southwestern Nevada. In these areas, carbonate, gypsum...

Rates of soil development from four soil chronosequences in the southern Great Basin Rates of soil development from four soil chronosequences in the southern Great Basin
Four soil chronosequences in the southern Great Basin were examined in order to study and quantify soil development during the Quaternary. Soils of all four areas are developed in gravelly alluvial fans in semiarid climates with 8 to 40 cm mean annual precipitation. Lithologies of alluvium are granite-gneiss at Silver Lake, granite and basalt at Cima Volcanic Field, limestone at Kyle...
