高分辨率遥感影像在新疆塔什库尔干地区沉积变质型铁矿勘查中的应用

Application of High-resolution Remote Sensing Images to Searching for Sedimentary- metamorphic Type Iron Deposits in the Taxkorgan Area, Xinjiang

采用Worldview-2、Quickbird高辨率分数据及Aster数据,开展了新疆塔什库尔干地区的沉积变质型铁矿遥感综合研究工作。在对研究区开展高分辨率遥感影像特征、遥感异常等成矿信息综合分析的基础上,以老并-赞坎铁矿区为例,建立了区域沉积变质型铁矿的遥感找矿模型,并利用该模型选择塔萨拉地区作为成矿有利地段进行了深入细致的研究,圈定了塔萨拉地区矿化蚀变带的分布范围。研究成果表明在布伦阔勒岩群南部的塔萨拉地区具有较好的寻找沉积变质型铁矿的前景。

Based on Quickbird/Worldview-2 high-resolution satellite images and multi-spectral remote sensing Aster images, this paper investigates the sedimentary-metamorphic type iron deposits in the Taxkorgan area, Xinjiang. Taking the Laobing-Zankan iron mine district as an example, we stud- ied its high-resolution satellite images and remote sensing anomalies and built a prospecting model for searching for sedimentary-metamorphic type iron deposits in this region. And we utilized this model to delineate the minerahzed alteration zones in the Tasala area. The result shows that the Tasala area south of the Bulunkuole rock group shows a good prospect of searching for sedimentary-metamorphic type iron deposits.
