在阐述双口山铅银矿成矿地质条件、岩(矿)石物性参数特征、地球物理场、地球化学特征的基础上,归纳总结了控矿地质因素和物化探找矿标志,从而建立了“双口山式”铅银矿的地质—地球物理—地球化学找矿模型。区域找矿模型为:滩间山群地层、韧性剪切带、高磁异常梯度带、显著的铅银元素地球化学异常。矿区银铅矿体找矿模型为:韧性剪切带内叠加的脆性断裂构造,宽振荡变化的高极化低电阻率带,铅、银、金原生晕异常,地表褐铁矿化带等叠合位置。
Based on the description of the metallogenic geological conditions, petrophysical parameter characteristics, geophysical field and geochemical characteristics of the Shuangkou Mountain lead-silver deposit, the ore-controlling geological factors and geochemical prospecting signs are summarized and established Geological - Geophysical - Geochemical Prospecting Model of “Shuangsankashan” Lead - silver Mine. The regional prospecting models are: Tanmushan group strata, ductile shear zone, high magnetic anomaly gradient zone, and significant lead-silver element geochemical anomalies. The ore-prospecting models for the silver-lead ore body are brittle fracture structures superimposed in ductile shear zones, high-polarization low-resistivity zones with broad oscillations, primary halo anomaly of lead, silver and gold, superimposed strata of limonite mineralization on the surface Co-location.
