“…Davidson (1963) surveyed uranium deposits in oxidized sandstones ranging from Paleozoic to Cenozoic age in several States across the United States and found selenium concentrations that ranged from 3 to 4,500 ppm. In a survey by Coleman and Delevaux (1957), selenium concentrations up to 3 weight percent were measured in uranium deposits of the Colorado Plateau.…”

Division; available at http://periodic.lanl.gov/images/periodictable.pdf.Cover. Dendrites, consisting primarily of naumannite (silver selenide) and lesser amounts of electrum, sphalerite, chalcopyrite, tetrahedrite, and other silver minerals (dark gray to black areas), quartz (light gray areas), and quartz and a minor amount of illite (beige to white areas). Sample is from the Buckskin National Mine, Humboldt County, Nevada. Photograph by Peter Vikre, U.S. Geological Survey.

“…Selenium is known to have volcanic, magmatic, and hydrothermal sources (Trelease and Beath, 1949;Coleman and Delevaux, 1957;Sindeeva, 1964;Howard, 1977) and is present in relation to hydrothermal and roll-type uranium deposits (Sindeeva, 1964;Fishman and others, 1985;Fishman and Reynolds, 1986). Selenium enrichment of geologic materials occurred during the Cretaceous age and was related to volcanic emanations of element-rich gases and ashes.…”

“…Selenium is present as a trace constituent in pyrite in the Mancos Shale within the study area; concentrations range from 0.003 to 1.6 percent (Coleman and Delevaux, 1957). When the Mancos Shale is exposed to weathering, selenium weathers (or is oxidized) from pyrite (where the selenium has a valence state of -2) to further transformations in valence state (-2 -> 0 -> +4 -> +6) that become increasingly more soluble with increasing valence: elemental selenium (Se°, selenium valence of 0), selenite (SeIVO32~, selenium valence of+4), biselenite (HSeIVO3~, selenium valence of +4), and selenate (SeVIO42~, selenium valence of +6).…”

“…Selenium is isomorphous with sulfur and substitutes in the crystalline structure of sulfide minerals (Coleman and Delevaux, 1957); therefore, core samples were collected to describe the relation of sulfide mineralization (and the source of selenium) to depositional environment in the Mancos Shale. Disseminated sulfides in the Mancos Shale core range in size from 0.01 to 0.05 mm viewed under 20X microscope.…”

-Important selenium data in the literature are discussed with reference to the biogeochemical processes affecting selenium cycling in wetlands. Selenium oxidation-reduction reactions are shown to be the most important biogeochemical processes controlling speciation, precipitation/ dissolution, sorption/desorption, methylation, and volatilization of selenium. Furthermore, bioavailability and toxicity of selenium, with reference to wetland ecosystems, are summarized. Based on the information available in the literature, a conceptual model depicting selenium chemistry and behavior in wetlands is described.
