Polydymite with Chalcopyrite on Dolomite, Sweetwater Mine, Ellington, Missouri, USA RARE
Polydymite is a rare nickel sulfide found in (1) carbonate depositional environments permeated by hot, saline metalliferous brine and (2) hydrothermal cobalt-nickel deposits. It has been identified as a mineral occurring in the Sweetwater Mine, a carbonate depositional environment, making this locality significant for those interested in collecting or studying this important mineral. While it is known to occur in the Sweetwater Mine, it is considered a rare find. This specimen was acquired from Jerry Carter/MineraLogic in 2013 and has remained uncirculated since.
