| 摘 要： | 桂东南混合岩区破碎带蚀变岩型金银矿床在混合岩田高、低级变质带过渡部位成矿,与燕山期混合花岗岩关系密切,赋矿空间为NE-NNE向构造断裂破碎带,常含方铅矿、闪锌矿、黄铁矿等金属硫化物.宽大的蚀变破碎带和黄铁绢英岩化蚀变是找矿的直接标志.

| Abstract: | The altered rock type Au-Ag deposits formed at transitional zone between intense and weak rnetamorphic zone in migmatite area in southeastern Guangxi Autonomous region. The deposits are closely related to Mesozoic Era migmatitized granite in genesis. The deposits were accumulated at NE -NNE faulted fracture zone. Galena, sphalerite,pyrite and some metallis sulfide generally are major ore minerals. Large and wide altered fracture zone and beresite altered zone is directly the indicator for ore deposit exploration. |
