摘要
从一个最初被标记为白云母的天然样本中发现了一个榴辉石晶体。与最初报道的 Cu62S32 相相比[Evans (1979). Z. Kristallogr. 150, 299-320]，正在研究的榴辉石晶体的细化成分为 Cu61.39S32，从而显示了铜的缺乏，据报道，Cu62S32 相中的所有原子位点都被完全占据。此外，目前的细化结果显示有八个铜位点分裂成对。
Natural djurleite with refined composition Cu61.39S32 revealing disorder of some Cu sites.
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.
