Abstract：Located in the East Kunlun orogenic belt of Qinghai Province, Asiha-Annage area is one of China's famous metallogenic belts. The geological structure in the area is complex, and the metal mineralization is also extremely rich. In addition, the metallogenic potential is tremendous. In order to establish a system of mineral combination evaluation method for gold exploration in the region, the authors established the metallogenic geological remote sensing information extraction scheme as the center of prospecting technology according to regional geological characteristics and metallogenic geological conditions in area from Asiha to Annage and in combination with the theory of deposit geological remote sensing. On such a basis, different resolution images such as QuickBird,ASTER and ETM+ were interpreted for the line-ring structure and tone anomaly in the whole study area. Furthermore, the authors analyzed the image characteristics of regional typical gold deposits, found the line-ring structure favorable for mineralization and delineated 20 prospective ore-search areas. A comparative analysis of the tone anomalies and geochemical anomalies shows that the degree of the coincidence between the two kinds of anomalies is high and significant to the high efficient ore prospecting.
