| 摘 要： | 通过钻孔与地面物性测定，查明含矿岩体和硅质板岩都具有较高的极化率和相对较低的电阻率，是引起电性异常的主要因素。利用重磁异常推断岩体的空间分布形态为一向下延伸长度大于走向长度的岩柱。由重磁异常圈定的岩体范围内电性异常为矿体引起，其外为岩性异常，这是区分矿与非矿异常排除干扰的最佳标志。

| Abstract: | By studying borehole data and by ground geophysical surveying,it is inferred that both ore bearing rockbody and siliceous slate are of relatively high polarizability and of relatively low resistivity,which are the major factors for causing electronical anomalies.The shape of the rockbody is a column like body which stretches downward and the downward length is greater than the length along its strike direction.The rockbody is confined by gravity magnetic anomaly and the electronical anomaly is caused by orebody within the rockbody. This is the best indicator for discriminating whether or not the anomalies related to mineralization. |
