摘要
独山玉矿区内岩石类型主要为次闪石化辉长岩、角闪岩及橄榄质科马提岩,岩石普遍呈碎裂、糜棱结构,总体属于铁质基性岩类.岩石蚀变普遍,特别是次闪石化遍及整个岩体.岩石是有明显的动力变质作用,显示出独山的个性格局.独山玉脉与次闪石化、钠黝帘石化和构造糜棱岩化关系密切.根据独山隐赋边界,推测整个基性岩区是玉石的成矿远景区.
The type of rock in Dushan Jade mine is mainly the gabbro of second-rate hornblend,hornblend and preridotite Kamet rock. The rock mainly shows smash,mini-edges and corners strure. It totally belongs to the typeof iron bedrock. The rock is widely corroded,espacialy the second-rate hornblende is all over the rock. The rock has clearly power changing function and it shows the personahty structure of Dushan mountain. The Dushan Jade vein is closly connected with the pertrifaetion of second-rate hornblende and mini-edges and corners structrue.According to the hidden border of Dushan mountain,it canrang area of Dushan Jade mineralization.be infer red that all of the bedrock area is the longrang area of Dushan Jade mineralization.
