衡阳盆地盐田桥矿区地质物化探综合找矿效果

盐田桥矿区位于铅锌多金属成矿富集区,成矿地质条件优越,矿区内铜多金属矿化受到断裂构造的严格控制。在306大队于矿区内开展的地质-物化探综合找矿工作的基础上,通过对该矿床进行地质特征分析、电法测量以及土壤地球化学测量,并结合矿床内岩(矿)石物性特征,认为矿床内矿体具有明显的一高(高幅频率)一低(低电阻率)地球物理特征和地表铅、锌、铜、钨等异常晕,并据此对盐田桥铜多金属矿床深部成矿潜力进行综合评价,为矿区下一步的地质找矿工作指明了方向。

The effects of geological-geophysical and geochemical integrated prospecting in the Yantianqiao deposit on the northern margin of Hengyang basin

The Yantianqiao copper polymetallic deposit is located in the Chaenshi lead?zinc polymetallic ore concentration area on the northern margin of Hengyang basin. Ore?forming geological conditions of this area are very good. Copper polymetallic mineralization is strictly controlled by faulted structure in this deposit. This paper is based on geological and geophysical?geochemical integrated geolog?ical prospecting work in the deposit conducted by No. 306 Geological Party. Through analyzing the geological characteristics of the de?posit as well as geophysical electric and geochemical soil survey, in combination with the rock ( ore) physical characteristics within the deposit, the authors consider that the orebodies in this deposit have some obvious geophysical characteristics such as one high ( high frequency) one low ( low resistivity) and lead, zinc, copper, tungsten and other elements anomalous halos at the surface. Mineralizing potential in the depth of the Yantianqiao copper polymetallic deposit is synthetically evaluated, and the prospecting targets are delinea?ted for future geological prospecting work.
