独山巴年锑矿断裂构造地球化学特征

Geochemistry Characteristics of Faulted Structure in Dushan Banian Antimony Deposit

用构造地球化学的理论和方法,解析巴年锑矿断裂构造与元素地球化学的内在联系及规律性,揭示断裂构造中元素的分配特征、锑在断裂构造中的异常特征,获得了独山锑矿构造岩中元素的R形聚类分析结果,巴年锑矿构造岩石中元素的R型聚类分析结果,独山锑矿田构造模拟实验结果。表明构造活动促使元素活化转移并在断裂构造带浓集,断裂构造对巴年锑矿形成有重要控制作用。

By using the theory and way of structural geochemistry,the relativity and regularity between faulted structure and geochemistry of element are analyzed,the characteristics of element distribution in faulted structure are described,and the unusual characteristics of antimony in faulted structure are indicated.The R-cluster analyses of structural rock in Dushan antimony deposit and Banian antimony deposit and the results of structure imitative experiment of Dushan antimony ore field are achieved.It is shown that tectonic activity makes element of oreforming activate and transform, and element of ore-forming is concentrated in faulted structure, the faulted structure plays an important role in formation of Banian antimony deposit.
