Attractive combination piece with pale yellow partly gemmy and quite lustrous crystals of calcite to 1.0 cm in size across the top of a thin matrix coated by pale pink lustrous crystals of dolomite. In good condition. Collected by Bill Mackenzie in July, 1994. The specimen comes with a previous label from the collection of Ray DeMark.The Corydon Crushed Stone Co. Quarry, located northwest of Corydon in Harrison County, Indiana, operates within Mississippian-age carbonate strata, primarily extracting limestone from formations such as the Saint Louis, Ste. Genevieve, and Paoli Limestones. Operating since the mid-twentieth century, the active commercial stone quarry has become widely recognized by mineral collectors for vugs and pockets containing exceptional specimens of pink dolomite, distinct calcite crystals, fluorite, and barite. While active commercial mining continues to supply aggregate materials to the region, the site is generally closed to outside mineral collecting.
