内蒙古花敖包特银铅锌多金属矿床容矿岩石地球化学特征

Geochemistry of Host Rock of Hua'Ao Bao te Silver-lead-zinc Polymetallic Deposit,Inner Mongolia

花敖包特银铅锌矿床位于内蒙古西乌珠穆沁旗宝日格斯台苏木境内,是一个近年来发现的与岩浆岩活动有关的热液脉状银铅锌多金属矿床.该文从花敖包特银铅锌多金属矿床地球化学数据出发,对矿区的地球化学体特征进行了分析研究.相对于中国东部陆壳丰度而言,本区容矿岩石强烈富集Ag、As、Pb、Sb、Zn(K1≥5);富集Bi、Cd、Hg、In、Sn、W(1.2≤K1<5).相对于容矿岩石而言,矿化岩石强烈富集As、Cd、Hg、In、Pb、Sn、Zn(K2≥5),富集Ag、Bi、Mo、Sb、W(1.2≤K1<5).矿区地层本身具有一定的成矿潜力.

Silver-lead-zinc deposit of Hua＇ao bao te is located in the region of Bao ri ge si tai Su-Mu at Xi Ujimqin Qi in Inner Mongolia,and is a newly discovered hydrothermal veiny silver-lead-zinc polymetallic deposit related to magmatic activitis.On the basis of geochemical data of silver-lead-zinc polymetallic deposit,this paper analyses the characters of geochemistry of mine area.Compared with the abundance of continental crust in eastern China,the host rocks in this area are strong enriched in Ag、As、Pb、Sb、Zn（K1≥5）,enriched in Bi、Cd、Hg、In、Sn、W（1.2≤K15）.Compared with compositions of the host rocks in this area,the mineralized rocks are strong enriched in As、Cd、Hg、In、Pb、Sn、Zn（K≥5）,enriched in Ag、Bi、Mo、Sb、W（1.2≤K5）.the stratum of the mine area have some of the ore-forming potential.
