摘要
新疆塔什库尔干地区的磁铁矿床是河南省地质调查院2003年在实施1/25万克克吐鲁克幅、塔什库尔干幅、莎车幅区域地质调查过程中发现的,也是迄今为止新疆南部最大的磁铁矿床。该矿床产出的大地构造位置独特,成矿地质条件良好,找矿潜力很大。本文根据最新找矿勘查资料,通过对矿区地质、矿体及矿石组构特征等方面的综合分析研究,认为新疆塔什库尔干地区磁铁矿床是沉积变质型磁铁矿床,区内进一步的找矿方向为古元古界布伦阔勒群第二岩性段分布的向形(斜)核部。
The Magnetite iron deposit located in the Taxkorgan region is the biggest magnetite ore deposit in the southern part of Xinjiang.It is found by Henan Institute of Geological Survey in 2003 during the 1/250 000 regional geological survey.The ？geotectonic position of the deposits is special,the metallogenic geological conditions are great,and there will be a giant potential for the prospecting.Based on the lastest prospecting exploration data of the depsosit geology,orebodys and ore-structure characteristics,it is concluded that the Taxkorgan magnetite iron deposit belongs to sedimentary-metamorphic type.Therefore,the further prospecting direction in this region should be focused on the synclines core area of the second lithologic segment in the Paleoproterozoic Bulunkuole Group.
