尖山银铅锌多金属矿床地质特征

GEOLOGICAL FEATURES OF THE SILVERLEADZINC POLYMETALLIC DEPOSIT OF JIAN SHAN

尖山银铅锌多金属矿床产出受ＮＮＥ－ＮＥ向蚀变破碎带控制，主要矿体产出受钙质千枚岩、大理岩岩性控制，矿化具有明显分带性，矿石类型有含金石英脉型、含银铅锌硫化物型和含银铜硫化物型。矿床成因为岩浆－地层双源的中高温变质（岩浆）热液充填交代成矿。

The AGPbZn polymetallic deposit of Jianshan is controled by the NNENE structural alterationrupture zone.The main orebodies occur in calcareous phyllit and marble.Obvious zoning is displayed in the mineralyzation.The ore types include goldbearing guartzvein,Agcontaining leadzinc,sulfides and Agcontaining copper sulfides.The genesis of the deposit belongs to mediumhigh metamorphic(magmatic)hydrothermal fillingreplacement type of magmastrata double sources
