摘要: 针对博格达南缘一带地形复杂、自然环境条件恶劣,分布有众多小型矿床及矿点,具有较好的成矿地质背景等特点,采用传统的地质找矿方法难度大.在对区城成矿地质条件综合研究基础上,通过对化探、遥感找矿信息的综合分析,发现化探异常主要位于构造和岩浆侵入接触带附近.利用GIS进行了成矿预测选区,圈定了5个具有成矿地质异常的找矿靶区,并厘定了各靶区的主攻矿种,为在本区进一步开展地质勘查工作提供了找矿依据和方向.Abstract: In spite of complicated lithological conditions and harsh natural environment, the south edge of the Bogda terrain is fairly good geological background abundant in small deposits and occurrences. Geological prospecting with traditional methods is difficult and infeasible in this area. Based on a comprehensive study of mineralization geological conditions, and through an integral analysis of geochemical prospecting and remote sensing information, it is found that geochemical anomalies are mainly located in tectonic and magmatic intrusive contact zone nearby. Metallogenic prediction constituency conducted by GIS delinated five prospecting targets with metallogenic geological anomalies and determined the main minerals of each target area. The research provides prospecting basis and direction for further geological exploration in this area.
