DescriptionLoellingite, FeAs2 (iron arsenide), is a mineral closely related to marcasite FeS2 (iron sulfide). It occurs in veins, including pegmatite, and in marble or skarn. Distinguishing loellingite from arsenopyrite can be difficult. This specimen, about 6 cm across consists almost entirely of fine grained loellingite.
