新疆地区西昆仑和田玉遥感信息提取与找矿远景区圈定
Extraction of Remote Sensing Information and Delineation of Prospecting Targets of Hetian Jade in West Kunlun,Xinjiang
摘要
Abstract
Hetian jade in Xinjiang was mainly produced in the area from West Kunlun to Altun.These areas are high altitude and cold regions,so it is difficult to carry out geological survey directly.The current remote sensing technology has made significant progress in the exploration of hydrothermal deposits.The Hetian jade deposit is a hydrothermal deposit,leaving obvious mineral alteration information on the surface.It is theoretically feasible to find the Hetian jade deposit through remote sensing information technology.In this study,in Kangxiwa area of West Kunlun,multispectral data such as S2A and ASTER and hyperspectral data such as Gaofen 5 are used to extract alteration information related to Hetian jade mineralization,build a remote sensing prospecting model based on alteration information,delineate several Hetian jade remote sensing prospecting prospect areas,and conduct field verification of prospecting prospect areas.In several selected Hetian jade remote sensing prospecting prospect areas,typical alteration types of Hetian jade deposit,namely serpentinization and tremolite,as well as marble outcrops and jade mines under mining,have been found.The field verification results show that the Hetian jade remote sensing exploration technology used in this study is effective.关键词
