石平川钼多金属矿区构造特征浅析
|
摘要
浙江省石平川钼矿位于浙江东南沿海火山活动带。通过研究表明石平川钼矿应为典型的石英脉型钼矿,该区含矿断裂构造以北西向为主,其次为近东西向、北东向、近南北向等。断裂的这些产出样式是受到区域应力场控制的结果。石平川火山穹窿的环状断裂发育于岩体的内、外接触带,空间延伸远,常由数条平行断裂组成长几百米~上千米,宽几十米的裂隙带,这些构造裂隙是石平川矿区主要容矿构造。
The Shipingchuan molybdenum ore is located in the volcanic activity belt along the southeast coast of Zhejiang.The study shows that the Shipingchuan molybdenum deposit should be a typical quartz vein type molybdenum deposit.The ore-bearing fault structure in this area is dominated by the northwest direction,followed by the east-west direction,the northeast direction,the near north-north direction and so on.These output patterns of faults are the result of regional stress field control.The annular fractures of the Shipingchuan volcanic dome developed in the inner and outer contact zones of the rock mass.The space extends far and often consists of several parallel fractures with cracks ranging from several hundred meters to several thousand meters in width and tens of meters wide.These structural fractures are the main ore structure in Shipingchuan mining area.
