Geochemical Modeling Methods of Predicting Trace Element Concentrations in Dexter Pit Lake, Elko County, Nevada.

摘要

Dexter pit lake, within the townsite of Tuscarora, Nevaada, ahs been in existence since 1990 and provides a natural laboratory for the study of cycles of trace elements associated with ore deposites (e.g. As, Cu, Pb, and Se). Our goal in this study is to develop and calibrate methods of geochemical modeling that may be applied to estimating the concentrations and fluxes of trace elements in pit lake systems. Our initial modeling work considers limnology, hydrology, wall rock mineralogy and geochemistry, benthic fluxes, and c olloid composition. Results from our work may be useful in evaluating water quality in the arid West.
