【摘要】 在安徽沙溪斑岩铜矿床凤台山矿段6线开展剖面磁法、激电、CSAMT和SIP等综合物探测量,总结了隐伏铜矿体引起的磁、电变化特征,建立了斑岩铜矿地球物理找矿模型,并将地球物理找矿模型在沙溪外围査巴岗地区开展找矿实践和检验。通过实践和检验,根据地球物理找矿模型中激电、CSAMT特征推测的隐伏闪长岩体已经得到验证,根据激电、SIP特征推测的非矿致异常也得到证明。更多还原

【Abstract】 This work conducts comprehensive geophysical surveys with the magnetic, IP, CSAMT and SIP methods in the Fengtaishan ore block of the Shaxi porphyry copper deposit along the prospecting line No. 6, and summarizes the magnetic and electric characteristics of the concealed copper ore bodies to build a porphyry copper ore geophysical prospecting model. This geophysical prospecting model has been validated in the peripheral of the Zabagang area. Through the practice and test, according to the geophysical prospecting model IP and CSAMT characteristics, the conjectural concealed diorite rock mass has been verified, and the inferred non-ore-causing anomalies from excitation current and SIP characteristics are also proved.更多还原
