Distribution Of Trace Elements In Host Rock Limestone In The Tri-State Zinc-Lead District, Dinesh Jashbhai Patel
Masters Theses
"The trace metal contents of limestone in the Tri-State zinc-lead district were determined within a single horizon, the M bed. Ninety-six specimens, collected for a previous study of their petrographic character, were analyzed for zinc, lead, and copper using atomic absorption spectrophotometric techniques.
The unaltered M bed limestone at a distance from ore bodies was found to contain only 12-28 ppm zinc, 40-SO ppm lead and 12 ppm or less copper. Those limestone specimens which were found b earlier petrographic study to be altered principally to sparry calcite commonly contain anomalous amounts of zinc and lead. Some also have slightly …
