Source Identification And Allocation Of Metals In Stream Sediments Using Electron Microprobe Techniques

Elevated concentrations of copper, cobalt, and arsenic within the Panther Creek Basin sediments in north central Idaho prompted an evaluation of the sources of the metals. Potential tailings and waste rock source samples collected at the head of Blackbird Creek were compared to sediment samples in the Panther Creek Basin using electron microprobe techniques. The mineral types, degree of alteration, and the morphology of the metal-bearing sediment grains within Blackbird and Panther Creeks were found to consist of copper-, cobalt-, and arsenic-bearing sulfide minerals.
