Barite on calcite, Elk Creek, South Dakota
description: 8" ac. Acquired from Robert Lavinsky in early 2010. Illustrated in "American Mineral Treasures". It is a wonderful specimen from one of America's top two localities for this common but popular mineral. Barite specimens of Elk Creek are removed from Septarian nodules. One repair is present on this piece. The repair is at the join between the left-most barite crystal and the matrix. The repair is clean.
