U.S. Geological Survey Open-File Report 2006-1184
Prepared in cooperation with U.S. Environmental Protection AgencyPreliminary Results of Sequential Extraction Experiments for Selenium on Mine Waste and Stream Sediments from Vermont, Maine, and New ZealandBy N.M. Piatak, R.R. Seal II, R.F. Sanzolone, P.J. Lamothe, and Z.A. Brown |

| We report the preliminary results of sequential
partial dissolutions used to characterize the geochemical distribution
of selenium in stream sediments, mine wastes, and flotation-mill tailings.
In general, extraction schemes are designed to extract metals associated
with operationally defined solid phases. Total Se concentrations and the
mineralogy of the samples are also presented. Samples were obtained from
the Elizabeth, Ely, and Pike Hill mines in Vermont, the Callahan mine in
Maine, and the Martha mine in New Zealand. These data are presented here
with minimal interpretation or discussion. Further analysis of the data
will be presented elsewhere. VIEW the report [1.1.-MB PDF file] DOWNLOAD Adobe
