| 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。 |
| 英文摘要: |
| Xizaogou, Laodaizhanggou and Wangpingxigou are the three typical meso-epithermal filling replacement vein Pb-Zn deposits in the southern Ruyang lead-zinc ore field. Tests show that rocks in the ore field are characterized by different electric parameters and the lead and zinc ore have the highest intensified rate and the lowest resistivity. Vice versus are the other low metal rocks. IP anomaly is obviously distributed as an East-West belt coinciding with the mineralized altered cataclastic rock zone. The near-field source tripolar IP surveys show better result in detecting shallowly or more shallowly buried Pb-Zn deposits thus electric method is an effective tool to prospect Pb-Zn deposit. Based on various rock electricity parameters of Xizaogou Pb-Zn deposit we have accumulated the geological and geophysical prospecting model of the southern Ruyang lead-zinc ore field is built. |
