"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 higher copper contents.
Anomalous amounts of zinc can be detected in limestone adjacent to most of the ore deposits included in this study for distances as much as 165 feet. The anomalous zinc may extend beyond the front of alteration of sparry calcite. Lead anomalies usually are essentially coincident with areas of altered limestone. Anomalous amounts of copper are restricted to positions near the ore bodies"--Abstract, page ii.
