Deskripsi

A djurleite crystal was discovered from a natural sample originally labelled as chalcocite. The djurleite crystal under investigation has a refined composition of Cu61.39S32, thus revealing a Cu deficiency compared to the originally reported Cu62S32 phase [Evans (1979). Z. Kristallogr. 150, 299–320], where all atomic sites are reported to be fully occupied. In addition, the current refinement revealed a splitting of eight of the Cu sites into pairs.
