Abstract:

Hatu-Baogu area in western Jungar as one of China's vital gold producing regions with a long history of mining gold holds a good geological conditions for gold mineralization. This paper, based on a summary of Au-Cu mineralization conditions, applies DPIS to forecast the potentials of Au-Cu mineralization in this area with six prospects recognized. Statistically, large gold deposits are found to occur in the basalt area where the EW, NW and NE faults are jointly developed. Small magmas and mediate-basic to basic-acid veins control the porphyry copper deposits. The outskirts of small magmas are favorable for quartz-and altered-type gold deposits. The eastern and southwestern BaobeiSaertuohai, Bozhiate and Miaoergou magmas are another place with potentials where needs further geological work.

Key words: Au-Cu deposit, mineralization conditions, forecast of mineralization, Hatu-Baogutu area, Xinjiang

摘要：

西准噶尔哈图—包古图地区是中国重要的黄金产区之一，采金历史悠久，金铜成矿条件优越。在对该地区金铜成矿条件分析总结的基础上，利用“矿床位置预测系统”（DPIS）对区内的成矿远景进行了预测，圈定找矿远景区6处。通过统计分析，发现哈图地区EW、NW、NE三组断裂交汇部位出露的玄武岩区控制了大型金矿床的产出；包古图地区小岩体及中基性—中酸型脉岩集中出露区控制了斑岩型铜（钼）矿床的产出，小岩体外围是寻找石英脉型、蚀变岩型金矿床的有利部位；此外，宝贝—萨尔托海、博孜阿特、庙儿沟岩体东侧及西南侧地区亦为有利成矿预测区，应加强其中的地质找矿工作。
