摘要:

522高地金矿床位于兴蒙造山带东段的多宝山—争光—八车力北西向构造成矿带,该成矿带内已发现多处矿床(点),具有较好的找矿潜力。该矿床为近年来新发现的金矿床,矿床类型为构造蚀变岩型,成矿时代为燕山期。矿区内已圈定金矿体2条、金矿化体8条,锌矿体1条、锌矿化体4条。矿体呈脉状赋存于蚀变花岗闪长岩中,北东向与北西向断裂交汇部位控制矿体的产出,硅化、钾化、绢云母化、绿帘石化与金矿化密切相关;1∶2万土壤地球化学测量结果显示,由Ag、Cu、Pb、Zn、Sb等元素组成的组合异常为良好的地球化学找矿标志;高磁低缓负异常场区、激电中梯极化率高值异常、电阻率低值异常梯度带附近为重要的地球物理找矿标志。

Abstract:

522 Highland Gold Deposit is located on the NW-trending Duobaoshan-Zhengguang-Bacheli tectonic metallogenic belt in the east section of Xingmeng orogenic belt,and has good prospecting potentials.The deposit is a newly discovered gold deposit.The deposit type is tectonic altered rock type and the metallogenic epoch is Yanshannian.There are 2 gold ore bodies,8 gold mineralization bodies,1 zinc ore bodies and 4 zinc mineralization bodies delineated in the district.The ore bodies occur in altered granodiorite in veins,controlled by the intersection of NE and NW-trending faults,and silicification,potassic alteration,sericitization and epidotization are closely related to the gold mineralization;1∶20 000 soil geochemical survey shows that Ag,Cu,Pb,Zn and Sb comprehensive anomaly is the good geochemical prospecting mark;areas adjacent to high magnetism low negative anomalous field,IP intermediate gradient parallactic polarizability high value anomaly,parallactic resistivity low value anomaly gradient zone are important geophysical prospecting marks.
