【摘要】：羊拉铜矿床是金沙江构造带内的代表性铜矿床,其矿体产出明显受到断裂及层间破碎带控制。本文重点对羊拉矿床里农—路农接合段的3450 m中段进行了构造地球化学研究,R型聚类分析和因子分析表明:该中段断裂构造岩微量元素主要表现为地层岩石微量元素组合(Nb、Hf、Ta、Zr、Rb、V、Sc、Th、Cs、Be、Ga、Li、REE、Ba、Cr、U、Co、Tl、Ge、(Ag、In、Sn、Cu)),中-高温成矿元素组合(Cd、Pb、Bi、Ag、As、Sn、In、Sb、Cu、Zn、Ge、Tl、Mo、U、(Co、Ga))和地质意义不明元素组合(Ni、Sr),揭示羊拉矿床的形成可能经历了成矿前期成矿元素的初步富集和成矿期退夕卡岩化过程中成矿元素的沉淀成矿。构造地球化学异常的分布则指示了找矿预测靶区。
