吉林省珲春杨金沟白钨矿区地质特征及找矿方向

The geologic features of the Yangjingou scheelite mining area,Hunchun, Jilin Province and direction for ore prospecting

杨金沟矿区白钨矿体产于下古生界五道沟群地层与印支期二长花岗岩内外接触带中。矿化类型为花岗岩中的白钨矿—石英脉和斜长角闪片岩、云母石英片岩、红柱石片岩中的白钨矿—石英脉。矿体受南北向、北西向断裂及裂隙构造控制,矿床成因为岩浆热液—层控与岩浆热液复合型。

The scheelite orebody of the Yangjingou mining area occurred in the contact zone of the lower Paleozoic Wudaogou Group strata and the Indo-Sinian adamellite. The mineralizing types are classified into the scheelite-quartz vein in granite and scheelite-quartz vein in amphibolite, mica quartz schist and andalusite-schist. The orebody is controlled by SN, NW faults and fissures, the ore deposit belongs to magmatic hydrothermalism-stratabound and compound magmatic hydrothermalism type one.
