中文摘要:
      激电联合剖面法是判断隐伏地质体产状时常用的一种物探方法,应用领域广泛。矽卡岩型矿床由于成矿具有不规律性,在勘探过程中矿体的倾向常常难以确定,利用矽卡岩型矿床矿化带部位激电联合剖面视极化率曲线“反交点”特征,分析和推断青海省格尔木市迎庆沟-景忍地区两个典型矿化体的倾向,进一步和已探明矿化带特征对比分析,总结激电联合剖面视极化率曲线在矽卡岩型矿床判断矿化体倾向的特点,为今后提高判断矽卡岩型矿床矿体倾向准确性提供依据。
英文摘要:
      IP joint section method is a commonly used geophysical exploration method to judge the occurrence of concealed geological bodies, which has a wide range of applications. In mineral exploration, skarn type deposits have irregular mineralization, and the tendency of ore bodies is often uncertain in the exploration process. Based on the characteristics of “anti intersection” of IP joint section apparent polarization curve in the mineralization zone of skarn type deposits, this paper analyzes and infers Qinghai Province In yingqinggou Jingren area, Golmud City, the characteristics of two typical mineralized bodies are further compared and analyzed with the characteristics of the proved mineralized belt, and the characteristics of apparent polarization curve of IP joint section in judging the tendency of mineralized bodies in skarn deposits are summarized, so as to improve the accuracy of judging the tendency of skarn deposits in the future.
