摘要
遥感找矿技术具有高效、便捷、信息丰富的特点,特别适合西藏高寒山区矿产勘查活动。以西藏白雄为研究区,选用ETM+影像数据,经过影像预处理得到研究所需基础图像。在充分分析研究区地质矿产资料的基础上,进行地层、构造的影像特征分析和资源潜力评价,圈定7处找矿靶区。该区有寻找中型以上的砂页岩铜矿的前景。为加速该区矿产勘查指明了方向。
Remote sensing prospecting technique was characteristic of high efficiency,convenience and abundant information;and it was suitable for mineral exploration in high and cold areas like Tibet.The authors took Baixiong of Tibet for example.With ETM＋image data and through image pre-processing,the basic image was got.Based on analyses of the geology and mineral resources information in the study area,the stratum,structure analysis of image characteristics and resource potential were evaluated,and seven predicting targets were delineated.It was concluded that a medium scaled sandy shale cupper deposit was possible to be found in the district.
