About AnomaliteHide

Named in 1876 by George Augustus Koenig from "anomalous" because the mineral did not give a characteristic chemical reaction for manganese because of the co-occurring nickel and cobalt (3%), although the mineral contained essential manganese (30%). Palache et al. (1944) placed anomalite as a variety of wad without data. The mineral composition of anomalite remains unknown despite its continued availability.
An earthy blackish brown to brown pseudomorph of jeffersonite.
