| 摘 要： | 遥感技术是地质矿产调查工作不可或缺的手段之一。以高空间分辨率(WorldView-2、QuickBird、IKONOS)和中等空间分辨率(ASTER、ETM+)卫星数据为遥感数据源,利用多元、多层次遥感技术,完成了西昆仑成矿带高分辨率遥感地质调查工作。制作了调查区1∶5万正射影像图,为遥感地质调查工作提供了既具有精确地理坐标,又能直观反映区域交通和地质灾害分布状况等信息的基础影像地图; 通过遥感地质解译和遥感蚀变异常信息提取,结合野外验证,基本查明了调查区区域(含矿/成矿)地质体、(含矿/成矿)地质构造的展布特征和遥感矿化蚀变异常信息的分布情况; 在典型矿床找矿模型、区域成矿分区、区域成矿/控矿要素分布特征等研究工作的基础上,开展了遥感找矿预测,并对部分遥感找矿预测区进行了野外验证和简易工程查证。本次调查共为调查区推荐3 349处遥感蚀变异常区,圈定146个找矿预测区,推荐16个区调/矿调工作优先部署区和30个一般部署区,充分发挥了遥感技术在区域矿产地质调查工作中的先行作用。

| Abstract: | Remote sensing technology is one of the indispensable means in the geology and mineral resources survey. The high spacial resolution satellite data, such as WorldView-2, QuickBird, IKONOS, and moderate resolution satellite data, such as ASTER, ETM+, are mainly considered as remote sensing data in this paper. High resolution remote sensing geological survey on west Kunlun metallogenic belt has been completed using multivariate and multilevel remote sensing technology. The orthogonal projection images at 1∶50 000 scale in this region have been made, to provide accurate geographic coordinates and directly reflect the status of regional transportation and distribution of geological disasters information. Combining remote sensing geology interpretation and anomaly extraction with field survey, the regional distribution of the metallogenic geological bodies, geological structure and mineralized alteration zones have been delineated. On the basis of the study of regional typical deposits, regional metallogenic zoning, and distribution characteristics of regional metallogenic/controlling factors, the remote sensing prospecting prediction is carried out, and the field verification and simple engineering verification in the partial remote sensing prospecting prediction area are done. 3 349 remote sensing anomaly areas have been recommend, and 146 forecasting areas have been delineated. Besides 16 priority deployment areas and 30 general deployment areas have been recommended. The remote sensing technology has played the leading role in the work of regional geology investigation and mineral exploration. |
