关于内蒙古巴林左旗白音诺尔铅锌矿外围锡多金属地质特征及成因的探讨

Discussion on the geological characteristics and genesis of tin polymetallic in the periphery of Baiyinnuoer Lead-zinc deposit,Balin Zuoqi,Inner Mongolia

文章通过对普查区锡多金属地质特征及成因分析,白音诺尔铅锌矿外围锡多金属普查区出露的地层主要为二叠系、侏罗系中、上统和第四系;构造较简单;岩浆岩发育;区内晚二叠统林西组含碳斑点板岩及碳质板岩和三叠纪花岗闪长岩是本矿床重要赋矿地层,该矿床成因类型为:高温气化-热液蚀变型矿床。

Based on the analysis of the geological characteristics and genesis of tin polymetallic in the general survey area,the exposed strata in the general survey area of tin polymetallic in the periphery of baiyinuoer lead-zinc deposit are mainly Permian,Jurassic,middle,upper series and Quaternary;The structure is simple;Magmatic rock development;The Lopingian Linxi formation carbonaceous spotted slate,carbonaceous slate and Triassic granodiorite in the area are important ore bearing strata of the deposit.The genetic type of the deposit is:high temperature gasification hydrothermal alteration deposit.
