Precambrian Silver-Tungsten-Tin Mineralization and Its Relationship to Granitic Magmatism in Southeastern Missouri, U.S.A.

The comprehensive investigations of the polymetallic ore deposits of the Silver Mine district have made it possible to: 1) identify nine minerals that were not previously known to occur in the ores, 2) determine the paragenetic sequence of the mineral deposition, 3) show that the minerals were deposited in several stages, 4) identify five silver-bearing minerals, 5) determine a wide range of depositional T and a moderate range of fluid inclusion salinities, and 6) indicate a probable relationship of these ore deposits with the Precambrian tin granites in the region
