摘要
通过对塔木典型MVT型铅锌矿床的有关岩矿标本和样品的光、薄片的岩矿鉴定,铅—硫同位素的测试以及稀土元素含量分析等手段,研究认为其成矿物质主要来源于前泥盆系古老基底以及早古生代奥陶系;在成矿作用过程中,喜马拉雅期逆冲推覆褶皱作用所引发的大规模热卤水运移、循环,导致了矿质的进一步富集、沉淀。
Based on the abundant information from rock-mineral identifying, Pb-S isotope measuring, rare earth element analysising about tamu MVT lead-Zinc deposit, we regarded that the minerogenetic materior came from the old foundation and Early Palaeozoic＇ s ordovician system of an-devonian , during the minerogenetic process, a grand gathering of hot brine＇ s moving, circulating leaded by Himalaya period＇ s reversed napped fold, especially when the oil field brine mixed with deeply liquid, which caused minerogenetic trotter enriching and precipitating.
