Calcite on Fluorite, Rosiclare Level, Main Orebody, Denton Mine, Ozark-Mahoning Company, Harris Creek District, Southern Illinois Medium/large cabinet 7.5 x 12 x 20 cm $450. Online 2/27
Lustrous, deep purple fluorite, crystals to 10 cm, with a sparkly druse of calcite and scattered micro chalcopyrite. There are two pronounced calcite casts: former crystals may have been barite but morphology is difficult to appraise. Pillar robbing from workings very near the shaft and most likely from the center drift in the heart of the major collapse structure. Minor cleaves on one crystal. Very beautiful and attractive specimen. Pillar robbing June, 1994. Betty Kalaskie Collection #42-232. Entered into Ross C. Lillie database as RCL2630.
