新疆富蕴县阿克塔斯金矿找矿靶区主要特征及找矿远景

阿克塔斯找矿靶区位于重要的额尔齐斯Cu-Ni-Mo-Au-Fe成矿带中。区域内主要分布有斜长花岗岩、二长岩，石炭统南明水组为区域上主要的赋矿地层。靶区内的铜金矿化主要分布在斜长花岗斑岩与千枚岩的接触带中。工作成果显示该找矿靶区存在明显的物探激电和磁法异常，物探异常区与化探异常位置套合较好，地表槽探与钻孔中见有明显金铜矿化。综合分析物探化探异常及矿化特征，认为该靶区斜长花岗岩脉是本区金铜矿化的成矿母岩，属于岩浆热液型金矿床，找矿远景较好。

Main Characteristics and Prospecting Perspective of Aketasi Gold Field Prospecting Target Area in Fuyun County, Xinjiang

Akatasi gold field prospecting target is located in Cu-Ni-Mo-Cu-Fe metallogenic belt of Irtysh.Plagioclase granite,monzonite are the main magmatic rocks in the area.However,the Nanmingshui formation of lower Carboniferous is the main ore-bearing stratum.Cu-Au mineralization of the target area is distributed along the contact zone of plagioclase granite porphyry and phyllite.Geophysical prospecting shows that there is definite anomalies of IP and magnetic prospecting,and the geophysical prospecting anomalies and chemical prospecting anomalies are superimposed together.There is visible Au-Cu mineralization in the trenching and drilling.Plagioclase granite dike is considered to be the source rocks of Au-Cu mineralization in the prospecting target area based on the comprehensive analysis of anomalies of geophysical prospecting and chemical prospecting,and mineralization characteristics.Therefore,the genetic type belongs to mesothermal lode and the area is worth the further geological prospecting.
