Barite on Fluorite and Galena, Henson Mine, Ozark-Mahoning Company, Pope County, Southern Illinois Miniature 1.8 x 3 x 3 cm $45. Online 10/22
The Henson Mine was operated by Ozark-Mahoning Company in the 1980s on the Shelby Fault System in Pope Cunty. As is typical of all vein-type deposits, specimens were rarely found in open pockets since the vein was typically mineralized from wall to wall. However, sometimes pockets were found and a few minerals collected (usually by geologists or a miner with an unusual interest for minerals). Note the two distinct phases of barite mineralization and matrix of cubic galena and colorless fluorite: all characteristic of this orebody. Rare and in great condition. Mined 1984. Ross C. Lillie Collection RCL0377.
