| 摘 要： | 新疆卡拉塔格地区位于东天山成矿带,地质矿产资源丰富,铜金及多金属矿床集中,找矿潜力较大。铜金矿床地表矿化蚀变现象明显,发育的褐铁矿化+黄钾铁矾化+绢云母化形成地物反射光谱特征,为高光谱遥感地空综合预测方法用于探测铜金矿化蚀变信息成为可能,并成为寻找铜金矿床的有效技术方法。本文在卡拉塔格地区开展了航空高光谱和地面高光谱在铜金多金属矿床找矿研究,分别采用Hy Map航空成像光谱仪和Field Spec Pro FR光谱仪,获取了研究区Hy Map航空高光谱数据、地面准同步定标数据、地面高光谱数据,提取并筛选了基于Hy Map航空高光谱影像的成矿有利蚀变信息,在此基础上对该区红山铜金矿床航空-地面高光谱提取的蚀变信息进行了综合剖析,并结合矿区地质背景,建立了红山铜金矿床高光谱遥感地空综合找矿模型,经对比分析在该区圈定了2处找矿预测区。说明高光谱遥感地空综合预测方法在该区得到了很好的应用效果。

| Abstract: | Kalatag area of Xinjiang is located in the east Tianshan metallogenic belt, where mineral resources are abundant, and copper, gold and polymetallic ore deposits have great prospecting potential. Copper and gold mineralization and surface mineralized alteration phenomena are obvious, and limonite mineralization + jarosite + sericitization assemblage has formed abnormal spectral reflectance characteristics, which are favorable for the utilization of hyperspectral remote sensing ground-air integrated prediction method to detect copper and gold mineralization alteration information. In this paper, the authors carried out air high spectrum and ground spectrum in search for copper gold polymetallic deposits. HyMap aviation imaging spectrometer and FieldSpec Pro FR spectrometer were adopted and, as a result, HyMap aviation high spectral resolution data, ground quasi-synchronization calibration data and ground hyperspectral data were obtained in the study area, whereas extracting and filtering were conducted based on HyMap aerial hyperspectral image of metallogenicl favorability alteration information. On such a basis, the air-ground hyperspectral comprehensive analysis was made for the Hongshan copper and gold deposit in the study area and, in combination with the geological background of the deposit, a hyperspectral remote sensing ground-air integrated prospecting model was established for the Hongshan copper gold deposit. On the basis of comparison and analysis, two prospecting targets were delineated. The application of hyperspectral remote sensing ground-air integrated prediction method in the study area shows a good application effect. |
