浙江乌岙铅锌矿原生异常特征与远景预测

Primary Anomaly Characteristics and Prospect Prediction of Wuao Lead-zinc Deposit,Zhejiang Province

浙江乌岙铅锌矿是一个隐伏层状热液型矿床,赋存于前震旦系陈蔡群混合岩化片麻岩层间剥离构造中。面积性构造裂隙岩石测量结果显示,矿区发育Pb、Zn、Ag、W、Sn、Cd、S、Se、Te、In、Cu、Bi、Co等元素异常,常量组分CaO、MgO、Fe_(2)O_(3)高值区和SiO_(2)、Al_(2)O_(3)、K_(2)O低值区套合部位为成矿有利区。在矿区西北部发现三处新的地球化学异常,推测深部可能存在隐伏矿体。

Wuao lead-zinc deposit in Zhejiang province is a concealed layered hydrothermal deposit,which occurs in the pre-Sinian Chencai Group mixed lithialized gneissic interlayer exfoliation structure.The measurement results of areal structural fracture rocks show that there are anomalies of Pb,Zn,Ag,W,Sn,Cd,S,Se,Te,In,Cu,Bi,Co and other elements in the mining area.The high value areas of major components CaO,MgO,Fe_(2)O_(3) and low value areas of SiO_(2),Al_(2)O_(3),K_(2)O are the favorable areas for mineralization.Three new geochemical anomalies were found in the northwest of the mining area,suggesting that there may be concealed ore bodies in the deep.
