花垣渔塘铅锌矿区经过多年的地质工作,取得了较显著的找矿效果,获得了大量的地质资料,为物探工作的开展创造了有利的条件。为了配合地质上寻找隐伏矿体,我们在前人采用激电中梯找同类矿床效果不理想的情况下,根据本区具体地电条件,选用激电测深,首先在已知矿体上进行试验,获得强度不大但十分明显的η_s异常,无矿地段没有η_s异常。在肯定了该方法的有效性后,即进行了全区激电测深扫面工作,在23平方公里范围内,圈定出三个异常带,包括八个局部异常。同时开展了η_s测深曲线解释方法的探讨,提出对η_s曲线进行转换,按电阻率测深曲线进行定量解释的方法。并根据本区特定
Huayuan lead-zinc mining area after years of geological work, has made more significant prospecting results, access to a large number of geological data, geophysical prospecting work to create favorable conditions. In order to cooperate with the geology to find the hidden ore body, in the previous case, when using the escalator ladder to find the similar deposit, the effect is not ideal. According to the specific geoelectric condition in this area, we choose the electro-acoustic sounding, first on the known ore body Test, to obtain the intensity is not obvious but obvious η_s anomalies, non-mine section without η_s anomaly. After affirming the validity of this method, we conducted an area-wide electro-acoustic sounding scanning and delineated three anomalous zones within 23 km2, including eight local anomalies. At the same time, the method of interpretation of η_s sounding curve is discussed, and the method of converting η_s curve and quantitative interpretation by resistivity sounding curve is proposed. And according to this area specific
