APPLICATION OF SENSE-REMOTING IN THE EXPLORATION FOR GOLD MINERALIZATION IN QINCHUAN-PINGWU AREA

Gold mineralizations in northwest Sichuan area are very abundant, more than 100 deposits are found so far. Most of them occurred in the border area of Sichuan, Gansu and Shanxi, which is the so-called "gold triangle" mineralization area. Since 1986, we have used TM, MSS satellite images of Landsat and conducted digital processing, geological tectonic interpretation and experimental studies of information selection for the first time in this area. The linear structures, ring structures and their relationship with the exploration for gold mineralization have been interpreted, TM information selection for alteration discussed, and the exploration model on sense-remoting images established. As a result, seven prospects are delineated within the studied area, as well as an altered mineralization is outlined.
