Trace Element Analysis Of Selected Springs In The Virgin River Basin, Mary Ann Yelken Jan 1991

Trace Element Analysis Of Selected Springs In The Virgin River Basin, Mary Ann Yelken

UNLV Retrospective Theses & Dissertations

Spring water from 23 springs in and near the Virgin River Basin (southwestern Utah, northwestern Arizona, and southeastern Nevada) was collected and analyzed for chemical concentrations. Trace elements and major ion chemistry was used to determine the potential for utilizing water chemistry to provide information on spring water source and flow pathways. Principal Component Analysis (PCA), rare earth element (REE) normalization patterns, and mineral equilibrium modeling (PHREEQE) techniques were used to analyze the data set. Four major spring water groups were displayed by the PCA, based on similarities in water chemistry. The analyses suggest that spring water chemistry is a …


Impacts Of The Little Ice Age On The Vegetation Of Southern Nevada, Kimberly Lynn Hunter Jan 1990

Impacts Of The Little Ice Age On The Vegetation Of Southern Nevada, Kimberly Lynn Hunter

UNLV Retrospective Theses & Dissertations

Fossil woodrat middens from a wash near Searchlight Nevada were used to reconstruct the timing and magnitude of vegetation change using Larrea tridentata, Coleogyne ramosissima, and Yucca sp. The study revealed that Coleogyne appeared in the midden at 600 {dollar}\pm{dollar} 50 yr B.P., and full Coleogyne community establishment occurred by 470 {dollar}\pm{dollar} 60 yr B.P. The increase in Coleogyne was coincident with the climatic shifts during the Little Ice Age, 1250 A.D. to 1800 A.D., and was probably caused by increased precipitation.

Investigations And Research In Nevada By The Water Resources Division, U. S. Geological Survey, 1982-83, Terry Katzer, Otto Moosburner, William D. Nichols

Publications (WR)

The Water Resources Division, U.S. Geological Survey, is charged with (1) maintaining a hydrologic network in Nevada that provides information on the status of the State's water resources and (2) engaging in technical water-resources investigations that have a high degree of transferability. To meet these broad objections, 26 projects were active in Nevada during fiscal year 1982 in cooperation with 36 Federal, State, and local agencies. Total funds were $3,319,455, of which State and local cooperative funding amounted to $741,500 and Federal funding (comprised of Geological Survey Federal and cooperative programs plus funds from six other Federal agencies) amounted to …
