摘要
通过对西藏林周地区有关矿床基本成因、蚀变特征和区域水热活动历史的调查,对其中一些矿床流体包裹体以及旁多、当雄、羊八井等地水样进行了H、O同位素分析,概略地在区域断裂构造网络中判断成矿流体运移趋势,归纳出喜马拉雅期林周地区新生代水热成矿的条件和环境,并建构了一个地质模型。
On the basis of studies of the basic genesis, alteration features and regional hydrothermal activities of related deposits in the Lhünzhub area, Tibet, hydrogen and oxygen isotope analyses have been performed on fluid inclusions of some ore deposits and water samples from Poindo, Damxung, Yangbajain around the Lhünzhub area, Tibet, the migration trend of ore fluids in the regional fault network has been broadly estimated, and the conditions and geological environment of Cenozoic hydrothermal metallogenesis in the Lhünzhub area during the Himalayan period have been summarized. On that basis, a geological model is constructed.
