Dark lustrous brown Sphalerite crystals to 3mm totally covering lumpy colloform growths of brassy Pyrite. Neat specimen!
The W. Fork Mine is located in the SE lead-district in Missouri and is also a Mississippi Valley Type deposit in the Viburnum Trend. According to a paper on the W. Fork Mine the presence of rapidly deposited, collorform ZnS and FeS is an indicator that the ore fluids which deposited the sulfides in the central zone were more saturated with respect to metal sulfides (email us for link to abstract if interested).

Absolutely perfectly formed modified tabular Sphalerite crystals with beveled edges in a cluster to 1.5cm set nicely on Limestone matrix with water clear Calcite rhombs. Very skillfully extracted, as there is no damage. The color is very dark red-brown that appears black, even under my intense photo lights. Superb specimen!
