The Remote Sensing Prospecting Information Extraction and Mineral Resources Prognosis in the Banqiao Rare Earth Mineral Deposit
摘要
Abstract
In this paper, the prospecting information of the rare earth resources on Earth' s surface was extracted by analyzing the metallogenic regularity and geological remote sensing features of the study area. Firstly, the distribution of geomorphic units of Qedl was interpreted based on SPOT imagery and slope map obtained from DEM data. Then, the distribution of characteristic minerals closely related to rare earth deposits such as kaolin, sericite and chlorite was extracted by using remote sensing alteration anomaly extraction methods in the study area. At last, the potential rare earth ore districts were predicted by using overlap analysis of geomorphic units of Qedl as well as slope and abnormal extraction results. A comparison with the results of geological and geochemical survey shows that the remote sensing methods proposed in this paper are effective and reliable in prognosis of rare earth mineral distribution at the scale of 1 : 50 000 and can provide useful suggestions for more detailed potential evaluation of rare earth mineral resources.关键词
