藏东三江地区遥感五要素模式找矿远景

藏东三江地区地质构造复杂,成矿条件优越,具备形成铜、金及铅 锌 银矿的地质背景,是中国重要的多金属成矿带。在进行藏东三江地区遥感解译编图与矿产资源预测的过程中,充分利用遥感信息丰富的特征,以遥感五要素找矿模式为技术手段,并结合该地区的地质构造与矿产类型、规模及分布特征,深入系统地阐明了测区的区域矿产地质特征、成矿地质背景和成矿、控矿条件;同时综合分析了区内已有的化探和物探资料,初步建立了遥感找矿模式,最后圈定出了5个遥感找矿远景区。

THE MINERAL-PROSPECTING PERSPECTIVE OF REMOTE SENSING FIVE FEATURES MODEL IN THE THREE-RIVER AREA OF EAST TIBET

The Three-River area of east Tibet is a very important mineralization belt in China. There have complex geological structures and the advantageous mineral formation-condition, especially has the mineralization setting for copper, gold, lead, zinc and silver minerals. This paper made good use of the abundance information on remote sensing, and combined the information of geological structures, mineralizing types, mineralizing scales and distributions to explain the mineralizing regularity in this area. We adopted the mineral-prospecting model of remote sensing five features as the main technique method, and integrated the geochemical and geophysical data for mineral-prospecting in this area. Finally, five remote sensing mineral-prospecting perspective zones in the area were pointed out.
