Biogeochemical Effect of Gold Deposit and Remote Sensing Information Extract
金矿生物地球化学效应及遥感信息提取

In vegetation district,as a result of that the plant absorb Au and associated elements of lock and soil,the contents of Au and associated elements,pigment,water surface temperature,and cells structure in leaves occur variations,even the plant cause abnormality of biogeochemical effect,thus it appear abnormality in the spectral information of TM image.This paper takes the Hetai gold deposit as researh target.According to these feature and difference,we extract the abnormal feature of biogeochemical effect using remote sensing image processing,and enclose the remote sensing abnormal areas of mineral,thus we achieve the goal to find hidden deposits in vegetation.Meanwhile we go on looking for mineral deposits in western Guangdong and Heilongjiang,and evaluate rapid two the remote sensing abnormal areas.The results proved that remote sensing technology is a rapid,accurate and economical method for applying to practice of looking for mineral deposits in vegetation district,the new way is explored to be looking for hidden deposits in vegetation district.
