【摘要】：太白地区是过去秦岭成矿带中尚未详探的地区,在系统搜集和研究陕西太白地区前人地质成果资料的基础上,结合最新的1/5万地面高精度磁法测量图,以金、铅锌矿为主要目标,兼顾铜、钼、钴等多种金属矿产.矿区地面高精度磁测结果表明,调查区磁场总体分布特征呈北西-东西向展布,与区域构造线方向一致,磁场分布特征与地层及岩体分布特征对应良好.根据磁场特征,结合地质特征,将磁异常划分为七个区(带).通过对局部磁异常特征的研究,预测一个甲类及一个乙类远景成矿区,为以后找矿提供思路分析,为该区后续找矿工作的进行提供参考.
[Abstract]:Taibai area is an unexplored area in the Qinling metallogenic belt in the past. On the basis of systematically collecting and studying the geological data of predecessors in Taibai area of Shaanxi Province, combined with the latest 1/5, 000 surface high precision magnetic survey map, Lead-zinc ore is the main target, taking into account copper, molybdenum, cobalt and other metal minerals. The results of high precision magnetic measurement on the ground show that the distribution of magnetic field in the survey area is NW-EW, which is consistent with the direction of regional tectonic line. According to the characteristics of magnetic field and geological features, the magnetic anomaly is divided into seven regions. The prediction of a Class A and a Class B prospective metallogenic area provides an analysis of the ideas for future prospecting and provides a reference for the subsequent prospecting work in this area.
