西灶沟、老代仗沟及王坪西沟铅锌矿是河南汝阳南部铅锌矿田中的3个典型中-低温热液充填交代型脉状铅锌矿床。电参数测试工作表明矿区各种岩矿石具有不同的电参数值,铅锌矿石激化率最高、电阻率最低,其他金属含量低的岩石则相反;激电异常呈明显EW向带状分布,其展布方向与矿化的蚀变破碎带一致;近场源三极激电测量反映浅部或埋藏较浅的铅锌矿床找矿效果较好,电法测量是寻找铅锌矿床的有效手段。文章基于西灶沟铅锌矿床岩矿石的电参数等地质-地球物理信息,建立了汝阳南部铅锌矿田的地质-地球物理找矿模型。
The Xixigou, Laode generation zhanggou and Wangping Xigou lead-zinc mine are three typical medium-low temperature hydrothermal filling dating-type vein lead-zinc deposits in the southern lead-zinc orefield of Ruyang, Henan Province. The electrical parameters test results show that the various rock ores in the mine have different electrical parameters, the lead and zinc ore have the highest kurtosis rate and the lowest electrical resistivity, while the rocks with the other metal contents are opposite. The anomalies show obvious EW band distribution The cloth orientation is consistent with the mineralized alteration and crushing zone. The near-field source tripoelectric measurement reflects that the shallow part or buried shallow lead-zinc deposit is good for prospecting, and the electrical method is an effective method to find lead-zinc deposits. Based on the geophysical and geophysical information such as electrical parameters of rock ore in Xixigou lead-zinc deposit, a geologic-geophysical prospecting model for the lead-zinc orefield in southern Ruyang is established.
