新疆明锡山地区锡矿成矿条件分析

星星峡地区是中国西部重要的成矿区带,具备极佳的成矿条件。其中明锡山矿区属星星峡金多金属成矿带,矿区内锡铜矿化主要与海西中晚期岩浆热液活动有关,锡铜矿化均赋存在绢英岩化蚀变岩内,受区域断裂旁侧发育的NE向张扭性次级断裂控制,并从岩浆岩、构造、热液蚀变、地球化学等方面探讨了找矿标志。

Analysis on Tin Metallogenic Conditions in Xishan Area in Xinjiang Uygur Autonomous Region

Xingxingxia area is an important metallogenic belt in western China with good ore-forming conditions. Mingxishan mining area belongs to Xingxingxia gold and polymetallic metallogenic belt. Tin and copper mineralization in mining area have close relation with middle and late Hercynian magmatic hydrothermal activity. Bothe tin copper mineralization occurredc in phyllic altered rocks and are controlled by tension-torsional secondary fault with the trend of NE developed at the side of regional fault. From the aspects of magmatic rocks, tectonic, hydrothermal alteration, geochemical conditions, prospecting criterias have been discussed in this paper.
