吉林省洮南市丁家围子含金破碎带及其物化探异常综合研究

Comprehensive study on gold-bearing fracture zone and geophysical and geochemical prospecting anomalies in Dingjiaweizi,Taonan City,Jilin Province

通过对本地区物化探资料的综合整理及地表工程与钻探工程的验证,在勘查区东部发现一条含金破碎带,长约4 km。与本区土壤化探金异常以及物探激电中梯极化率异常和电阻率异常位置基本吻合,属构造控矿,主要受北北东向构造影响。此次目的是通过地质工作和物化探工作的综合研究,找出在地表以及地下垂直方向,不同岩性中物理性质和化学性质的特征,总结出矿体的成矿规律以及围岩的特点,为进一步工作以及寻找同类型矿种提供线索。

Based on the comprehensive arrangement of geophysical and geochemical exploration data and the verification of surface engineering and drilling engineering in this area,a fracture zone containing Au,about 4 km long,was found in the Eastern of the exploration area.It is basically consistent with the Au anomaly of soil geochemical prospecting and the anomaly of ladder polarizability and resistivity in the IP of geophysical prospecting in this area,which belongs to the structure controlling ore and is mainly affected by the NNE trending structure.The purpose of this study is to find out the characteristics of physical and chemical properties in different lithologies on the surface and underground vertical direction through the comprehensive study of geological work and geophysical and geochemical exploration,and summarize the ore-forming rules and surrounding rock characteristics,so as to provide clues for further work and search for the same type minerals.
