Mineral Specimen #5346 Dogtooth Calcite on Fluorite Coated with Bitumen on Barite
Hardin Co., Illinois
Ex. A. Neely, Wrapped in Hardin County Independent newspapers, 1963
Sharply terminated, well formed Calcite crystals which are white to clear in color are perched on the side of a Fluorite crystal. The Fluorite is covered with a thin layer of Bitumen and is a light straw yellow/tan color underneath the bitumen. The Fluorite formed on white colored, massive Barite. The specimen was in a box of stock purchased by Aaron Neely and apparently never opened. Specimens were stacked in layers of newspapers which were badly decomposed. These papers were from the Hardin County Independent from 1963.
Flaws: Some of the terminations of the Calcite crystals are cleaved.
