摘要
本文对云南兰坪—思茅盆地脉状铜矿床中黝铜矿系列矿物的组成、时空变化特征及组分间的关系作了系统阐述。结果表明，本区脉状铜矿床中的黝铜矿系列矿物以砷黝铜矿［Cu12（As，Sb）4S13］占优势；系列组分本身具有明显的时空分带性；黝铜矿系列组分中Ag与Sb之间呈明显的正相关，而Ag与Cu之间呈明显的负相关。以上结果为本区铜矿床成因的确立及实际找矿提供了重要依据。
Electron microprobe analysis was conducted to study the composition of tetrahadrites fromLanping-Simao vein copper deposits, Yunnan Province. Experimental results showed that tennan-tites [Cu12 (As,Sb)4S13]are dominant and temporo-spacial variations in composition of tetrahedritesare noticed in these deposits. The content of Ag is positively correlated with that of Sb and nega-tively with that of Cu in tetrahedrite. The results presented in this parer are of important signifi-cance in establishing the genesis of and providing new clues to this type of copper deposits.
