| 中文摘要: |
| 以印度尼西亚西加里曼丹SANGGAU地区SPOT-5遥感图像为数据源，采用4（R）1（G）2（B）合成方案及相关遥感数据处理方法，考虑了该地区地形地貌特征、红土型铝土矿成矿背景及控矿因素，结合DEM三维可视化技术，建立了遥感找矿标志，总结了控矿母岩及其他岩性的影像特征，确定了遥感找矿预测靶区并圈定了矿体，所圈矿体与浅井验证工程结果吻合度达75%以上，为快速准确的探明印度尼西亚加里曼丹地区红土型铝土矿提供了新思路。二维和三维技术相结合的方法为此类受制于地形地貌的矿种提供了一种新的找矿途径。 |
| 英文摘要: |
| This work used the remote sensing data SPOT-5 and the synthesis method 4（R）1（G）2（B） to conduct a ore-search survey in the Sanggau area of western Kalimantan, Indonesia. It considered the terrain features, ore-controlling factors and metallogenic background of lateritic bauxite in this area, and combined the DEM 3D visualization technology. The results include establishment of the marks for remote sensing-based prospecting, summary of image features of ore-control host rock and other rocks, determination of target areas for ore search, and delineation of ore bodies. The consistency degree between the prediction and shallow-well verification is more than 75%. This work provides a new thought line for prospecting of the lateritic bauxite in the Kalimantan area. It also indicates that the combination of 2D and 3D methods can offer a new approach for prospecting of the ore limited by topography like the study area. |
