Barite on Calcite, Annabel Lee Mine, Ozark-Mahoning Company, Harris Creek District, Southern Illinois, Mined c. late 1980’s, ex. R. E. Pickens, Ron Roberts Collection CB-15, Miniature 4.5 x 5.0 x 6.5 cm, $45. Online 5/11.
A neat example of "snow on the roof" barite on calcite. In this case the specimen would have been oriented with the barite side up, leaving the underlying calcite uncoated. In excellent condition.
