我国西南地区斑岩矿床与走滑断裂关系及其勘查意义

我国西南地区是我国重要的斑岩矿床勘查开发基地,自20世纪60年代以来,相继勘查发现了玉龙、驱龙、普朗、多不杂等特大型斑岩铜矿。初步研究表明,西南地区斑岩矿床的集聚与走滑断裂存在着密切的空间关系。认识并深入研究斑岩矿床与走滑断裂存在着的这种关系,对于斑岩矿床勘查具有重要的意义。在西南地区现有的5个斑岩成矿带开展斑岩矿床勘查时,在沿区域性走滑断裂方向勘查并加强对走滑断层带内或其周围派生的局部引张或挤压地区开展找矿的同时,还应注意开展对鲜水河-小江左旋走滑断裂带及两侧斑岩矿床的勘查。

Relationship Between Porphyry Deposits and Strike Slip Faults and Its Implications to Exploration in Southwestern China

Southwestern China is a vital area for exploration and exploitation of porphyry deposits.Since the 1960s,a lot of large-scale porphyry deposits have been found in this region,such as the Yulong,Qulong,Pulang,and Duobuza porphyry copper deposits.Our preliminary study indicates that the occurrence of the porphyry deposits has a close spatial relationship with the regional-scale strike slip faults.The recognition and detailed study of this relationship has great significance for the exploration of the porphyry...
