Eastern oil shales including the Chattanooga Shale in Tennessee and the various other time-equivalent black shales in the central portion of the United States represent a major source of hydrocarbons. A primary concern for the development of eastern oil shale and all fossil fuels is the high concentration of sulfide minerals and associated with these materials. The objectives of this study were (1) to evaluate trace elements in sulfide minerals from a Chattanooga Shale core from central Tennessee and (2) establish mineral residence and stratigraphic distribution of selected trace elements. Previous researchers have suggested the residency of the trace elements As, Cu, Cd, Pb, Mo, Ni, and Zn as being sulfide minerals, either as separate distinct phases, inclusions, or isomorphous substitution. The most significant contribution derived from the present study is the direct observation and association of selected trace and minor elements with sulfide minerals. Rather than an indirect or inferred trace element- sulfide mineral association, sulfide mineral phases were isolated allowing the morphology and composition to be directly evaluated. 9 refs., 31 figs., 3 tabs.
