| 中文摘要: |
| 文章以西藏念扎金矿为研究对象，提出在传统矿产勘查的地质填图、找矿预测等项工作中适宜多源遥感数据的介入。地质填图主要采用高分辨率遥感影像，以人机交互解译为主要方法；遥感找矿预测主要采用多光谱影像，通过寻找与成矿相关的特征矿物的光谱特征，反演目标矿物地表分布情况，从而提供找矿线索。结合传统工作手段验证遥感技术所获取的成果具有较强的可信度。 |
| 英文摘要: |
| Multi-source remote sensing data is properly introduced and applied to the traditional geological mapping and ore prediction during prospecting at Nianza gold mine. For geological mapping are mainly the high-resolution remote sensing image interpreted by human-computer interactive results and multi-spectral image for ore prediction. Spectral characteristics of the ore-related minerals are determined and inversion of the goal minerals' spectral inversed to show their ground distribution so as to provide the prospecting clue. The interpreted result of remote sensing data that is checked with the troditional methods is with high confidance. |
