摘要
华南成矿省滇东南成矿带是国内大型超大型矿床较多地区,以往认为其成因与滇东南三大花岗岩体的侵入有关,但从上世纪80年代以后,不少科研单位及学者在3个超大型矿床的块状硫化物矿石中发现了喷流沉积的重要证据。白牛厂V1矿体的直接顶、底板地层,在多个穿矿钻孔中发现三叶虫化石以及在白羊矿段矿石中发现了沉积锡石等也难与阿尾隐伏花岗岩体的成矿作用相联系。
There are many large and super-large ore deposits in the SE Yunnan metallogenetic zone of South China metallogenetic province.In the past opinion,the genesis of them is related to the intrusion of 3 large granite bodies.However,the important witness of effusive sedimentation has been discovered in the massive sulfide ore of 3 super-large ore deposits by many research organism and people since 1980s.The trilobite fossil in the direct top and bottom rock beds of ore body Ⅵ of Bainiuchang has been discovered in the drilling hole and the sedimentary cassiterite has been discovered in the ore of Baiyang ore block,which are difficultly related with the metallogenesis of Awei blind granite body.
