Abstract

Pseudohexagonal twins are common in djurleite; crystal blocks are rotated relative to each other around [100], the normal of the close-packed layers, by multiples of 60°. Djurleite and digenite (dg) bands are intergrown, with (111)_dg parallel to (100)_dj, thereby creating a cubic-hexagonal alternation in the sequence of close-packed layers. The typical orientational relationship between coexisting djurleite and chalcocite is where [001]_cc is parallel to [100]_dj and [010]_cc is parallel to one of the <010> or <012> directions of djurleite. -from Authors
