摘要
甲乌拉银铅锌矿床与燕山期火山、次火山岩浆活动有关,并严格受北西向张扭性构造、层间构造及受潜火山影响的放射状、环状构造破碎之复合作用控制,矿床呈脉状产出,银与铅铜等元素呈互为消长关系。岩石化学、同位素地质学及包体研究表明:矿床成因与次火山系列斑岩体育密切关系,是典型的次火山热液脉状矿床。
The Jiawula silver-lead-zinc deposit is related to Yanshanian volcanic and subvolcanic magmatic activities and strictly controlled by compound action of NW-trending tenso-shearing structures and interlayer structures as well as radiate and ring fracture connected with subvolcanism. It occurs in the veinlike form, and Ag exhibits synchronous growth and decline relationship with Pb, Cu and Zn. Petrochemical, isotope geological and inclusion studies indicate that the ore deposit has much to do with the porphyry body of subvolcanic series and is hence a typical subvolcanic hydrothermal veinlike ore deposit. Based on these data, the authors put forward some criteria and promising areas for ore-prospecting.
