摘要
老金场金矿位于塔里木-中朝板块俞井子-柳园陆内复式裂谷带中,地处甘肃省瓜州县境内,矿床产出于下二叠统哲斯群中,由火山岩段和碎屑岩段组成。矿床控矿因素为地层、构造、岩浆岩及围岩蚀变,其中断裂构造是控矿的主要因素,它控制了矿体的展布范围及具体特征。
Laojinchang gold deposit is located in the inner compound rift belt of yujingzi-liuyuan land in the tarim-China-Korea plate,and in guazhou county,gansu province.The ore-controlling factors of the deposit are stratum,structure,magmatic rock and wall rock alteration,among which fault structure is the main factor of ore-controlling.
