Hyperspectral Remote Sensing Geological Interpretation And Prospecting Prediction In Yumengsu Area, Xinjiang, China

Xinjiang Ya Mansu region is located in the eastern Tianshan orogenic belt in the metallogenic belt, this area is rich in mineral resources, but poor natural conditions, for the district to carry out prospecting work, the hyperspectral remote sensing technology reflects the obvious advantages.(1) the HyMap hyperspectral data radiometric calibration, atmospheric correction and geometric correction pretreatment, and data quality analysis, ensure the quality and accuracy of hyperspectral data, the eclipse change information extraction of minerals has laid a good foundation;(2) MNF、PPI and N-D Visualizer, the endmember selection, in the spectral analysis based on, using SAM of mineral identification and mapping work, and the preparation of the alteration mineral distribution map;(3) Application of hymap hyperspectral remote sensing data of the study area distribution of limonite, jarosite; montmorillonite, muscovite; chlorite, epidote the mapping, the results and related data anastomosis;(4) Through the comprehensive analysis of faults, folds, and circular structures, re recognize the regional geological features, initially established the tectonic events in the region, as follows:to the north and south, North West to extrusion extrusion;(5) On the basis of the analysis of characteristics of the typical deposits, in typical ore deposits in southern alteration mineral identification, remote sensing anomaly analysis and interpretation of remote sensing geology on the basis, combined with field experiments, were delineated two favorable prospecting areas, pointed out the direction and target for the deployment of Geology and mineral resources investigation;(6) After a comprehensive data analysis and translation of the remote sensing, the study area is located in the western part of a composite syncline. Find favorable exploration area of area Ⅰ is mainly composed of Yamansu group composition, the core as the elegant full Su group sixth lithologic section, along the east-west axis, north wing, followed by the distribution of Ya ManSu group the first lithologic section to the five lithologic section, south wing, only full Su fifth group formation and unconformity on the lower Permian system the Burak group; syncline prominent westward turning end is narrow. Looking for favorable exploration area Ⅱ region mainly by the unconformity on the upper Permian hot springs group composition.
