ANGLESITE



Anglesite, a lead sulfate mineral of the barite group, was first reported from Sterling Hill by Palache (1935) and from the Buckwheat Dump in Franklin by Cook (1973). It occurs as euhedral colorless crystals, illustrated by Palache (1935).
No physical or optical data have been reported. At Sterling Hill, anglesite occurs as an alteration of galena in the Noble and Passaic Pits. At Franklin, it was found as microcrystals associated with malachite and cerussite in vugs in a galena-chalcocite vein cutting garnet-pyroxene rock. It is a rare mineral locally. (Dunn, 1995)
