摘　　要：大团山层状铜矿床位于铜陵狮子山矿田内,矿体主要呈透镜状、似层状赋存于三叠系殷坑组地层中,与矿化有关的岩浆岩为燕山中晚期石英闪长岩。在前人研究工作的基础上,试图通过大团山层状矿床的矿床地质特征、矿石矿物稀土元素组成和硫同位素示踪研究,深入探讨大团山层状铜矿的成因。Datuanshan strata-bound copper deposit, which has genetic links to late Yanshanian quartz diorite, occurs in Shizishan orefield, and the ore bodies, commonly lenticular or quasi-layered, principally lie in Yinkeng Formation of Triassic strata. Based on the former relevant studies, the authors provided insight information on ore geology, REE and sulfur isotope compositions of ore minerals to further discuss the genetic origin of Datuanshan strata-bound copper deposit.
