摘要:
为了解高分一号(GF-1)卫星影像的应用性能和查明新疆索拉克地区的成矿地质环境和规律,利用GF-1影像对该地区的控矿地质单元进行详细的遥感解译,结合ETM+多光谱遥感影像和航空高光谱数据,进行找矿应用.在新疆阿尔金成矿带的索拉克地区,利用多源遥感影像数据,开展了控矿地质单元遥感解译,通过综合研究控矿地质单元的遥感解译地质特征、遥感影像特征和遥感蚀变矿物特征,进一步构建遥感解译找矿模型.利用该找矿模型,在索拉克周边区域圈定了多金属找矿预测区,通过野外查证,新发现铜、金等多种金属矿化线索,取得了较好的找矿效果.
Abstract:
In order to understand the performance of GF -1 satellite image and find out metallogenic geological environment and regularity, the authors used GF-1 image to make detailed remote sensing interpretation of the ore-controlling geological unit in this area and, in combination with ETM+ multi-spectral remote-sensing image and aerial hyperspectral data, carried out ore -prospecting work. In Suolake area along the Altun gold metallogenic belt, the authors used multi-source remote-sensing data to carry out remote-sensing interpretation of the ore-controlling geological unit. Based on an integrated study of geological characteristics, remote - sensing image features and remote - sensing altered mineral characteristics of ore - controlling geological unit from remote -sensing interpretation, the authors further constructed remote-sensing interpretation ore-prospecting model and, with this model, delineated the polymetallic prospective area in the periphery of Suolake area. Through field verification, copper and gold polymetallic ore clues were discovered, thus achieving relatively satisfactory ore -prospecting result.
