摘要
滇西中新生代红层中的改造型铜矿床，在矿物组合上以大量富集黝铜矿族矿物为特色，主要包括砷黝铜矿和黝铜矿，且是矿石中最主要的组分。本文对其物理和化学特征、同位素组成进行了研究，指出它们在形成上与岩浆热液作用无关，是热卤水成矿的结果。
In mineral assemblage, the reformed Cu deposit in Mesozoic-Cenozoic red-beds of W Yunnan is Characterized by extensive enrichment of the tetrahedrite family, which mainly includes tennantite and tetrahedrite and is the most important component of the ore. In this paper, we have a study on the phsical, chemical property and isotopic composition of them and paint out that they have no relation to magmatic hydrothermalism in their formation but result from the mineralization of hot brine.
