高精度磁测在鄯善县大黄滩一带的找矿效果分析

Analysis on prospecting effect of high precision magnetic survey in dahuangtan area of Shanshan County

工作区位于吐鲁番-哈密盆地之南,矿带属古亚洲成矿域。位于阿其克库都克大断裂以北,暂未发现构造断裂,区内大面积出露下石炭统雅满苏组地层,南部见钾长花岗岩;阿奇山南工作区内大面积出露下石炭统雅满苏组一段地层,所在成矿带矿产丰富,已知矿产以铁为主,其次为金、铜,已发现的金属矿种有铁矿26处,金矿25处,铜矿8处,属于成矿较为有利地区,在以往年度综合物探工作的基础上,在大黄滩一带进行调查评价工作。

The working area is located in the south of Turpan Hami basin,and the ore belt belongs to paleo Asian metallogenic domain.Located to the north of Aqike kuduke fault,no structural fault has been found.In the area,lower Carboniferous Yamansu formation strata are exposed in large area,and potash feldspar granite is found in the south.The first member of Lower Carboniferous Yamansu formation is exposed in a large area in the South working area of Aqishan mountain.The metallogenic belt is rich in mineral resources,and the known minerals are mainly iron,followed by gold and copper.26 iron ores have been found,There are 25 gold deposits and 8 copper deposits,which are favorable areas for mineralization.Based on the comprehensive geophysical prospecting work in previous years,the investigation and evaluation work in dahuangtan area is carried out.
