| 中文摘要:高光谱遥感是当前遥感地质领域应用的前沿和热点, 目前国内外都在积极进行探索。高光谱遥感技术的发展为遥感的直接找矿带来了新的希望, 航空高光谱遥感技术由于可以获得高空间分辨率(可达亚米级)的高光谱遥感数据, 能够识别规模小的近矿围岩蚀变, 从而具有直接找矿的效果。直接找矿的核心是对矿产的预测, 预测效果是矿产勘查取得突破的关键环节。本文利用核工业北京地质研究院遥感信息与图像分析技术国家级重点实验室的CASI/SASI/TASI(可见光-近红外, 短波红外, 热红外)航空高光谱成像系统, 在甘肃北山柳园—方山口和新疆雪米斯坦地区获取的航空高光谱遥感数据, 对固体矿产预测技术进行了研究, 建立了基于航空高光谱遥感的成矿环境分析法、矿床定位模型识别法和含矿构造追踪法等预测方法, 并对每种方法进行了应用示范, 共发现7处金属矿化地段, 取得了明显的找矿效果。该项成果不仅为研究区的进一步找矿提供了新的有利地区, 而且建立的预测方法, 将会助力于高光谱遥感技术在其它地区的推广应用。 |

| Abstract:Airborne hyper-spectral remote sensing technology is a frontier and hot topic in geological remote sensing application, which attracts numerous attentions all over the world. This technology can obtain images with high spatial and spectral resolutions, which permits mineralization-associated alterations with small scales to be recoganized, thus provides a good assistance for ore prospecting. The core of ore prospecting is mineral prediction and the effect is key link for the breakthrough of mineral exploration. In this study, the authors put forward several methods, such as metallogenic environment analysis, ore deposit locating model, and tracking of ore bearing structures, for ore prospecting in the Liuyuan–Fangshankou and Xiemisitan areas based on the airborne hyper-spectral remote sensing images obtained by using CASI/SASI/TASI spectrometers of China National Key Laboratory of Science and Technology on Remote Sensing Information and Image Analysis. Application examples, in which 7 ore prospects were identified, demonstrated that the methods presented in this study are valuable for ore prospecting, and the achievement can be further used in other areas. |
