Marcasite from
Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA

Locality type:Park
Classification
Species:Marcasite
Formula:FeS2
Comments:"Large nodules of botryoidal marcasite, small vein fillings of the same material" (Hobbs, 1901), "Marcasite, more or less weathered, is abundant in the upper mine opening and in the north end of the lower opening. Here it occurs in granular masses and also as internally fibrous mammillary crusts a half inch in thickness on the walls of narrow open cracks in the lower limestone bed. It is very prone to oxidize under the action of the weather, and most of the abundant ocherous limonite stains present have come from its alteration." (Shannon, 1921b).
Habit:botryoidal, mammillary, granular
Quality for species:Poor for species, only of interest for locality collectors. (#)
Confirmation
Validity:Believed Valid
