1、xxxxx业论文摘要新疆阿克陶县阿尔巴列克铜铅矿区北为塔里木西缘喀什坳陷，南为西昆仑构造—岩浆带，其间即为奥依塔格-库尔良裂陷槽，阿尔巴列克铜铅矿区位于该裂陷槽中部。矿区铜、铅矿含矿层位为下石炭统霍什拉甫组第四岩性段第一亚段，下部灰黄色厚层破碎蚀变灰岩，上部盖层为灰黑色炭质粉砂岩、泥岩，下部围岩为灰绿色粉砂岩、细砂岩。铅矿化分布靠近于炭质粉砂岩、泥岩与灰岩接触面附近；铜矿化分布靠近于粉砂岩、细砂岩与灰岩接触面附近；有上铅下铜的分布特征。矿区总体构造及地层分布有向北撒开、向南收敛，北宽南窄的特征。主要以复式褶皱和北北西向断裂为主。在阿尔巴列克矿区
2、及周围分布有许多辉绿岩以岩脉、岩枝的形式出露，与成矿有密切联系，矿区出露的辉绿岩是地幔柱、地幔热点活动的产物，为热卤水循环及成矿物质聚集提供了热动力。据此，阿尔巴列克矿床成因类型可归为MVT型海相热水沉积砂页岩—碳酸盐型矿床。关键词：阿尔巴列克铜铅矿；裂陷槽；构造；热动力；MVT型ABSTRACTAkto County, Xinjiang the Aerba lek copper galena north western margin of the Kashi Depression, Tarim, South West Kunlun tecto
