Open full text 23 citations

Abstract

Djurleite, a new copper sulphide of or about Cu1.96S composition, is described. Chalcocite-like materials from several localities in Japan and in U. S. A. are identified as the new phase first synthesized by Djurle. The density is 5.63. The X-ray powder data are in complete agreement with those given by Djurle. The symmetry is orthorhombic. The composition is not accurately determined but appears to be approximately Cu1.96S. Djurleite is found as a primary and secondary mineral associated with one or more of the following mincrals: digenite, bornite, chalcopyrite and pyrite.
