Abstract

Abstract

Tuotuohe is located at the north-west section of "Sanjiang" metallogenic belt, Qinghai Province.This area boasts favorable mineralization background and great ore mineral potential.Prospecting targets for large-and/or middle-sized lead, zinc, sliver, and copper deposits have been delineated.Tuotuohe area belongs to cold grassy highland where some of the traditional geological field survey and mapping are difficult to conduct.Remote sensing technology is expected to provide low cost and efficient means to facilitate mineral exploration.Based on the spectrum information of mineral associations involved in mineralization-associated alteration zones and with the support of ENVI software, the authors used an integrated masking-principal component analysis-histogram classification (MPH) method to process the TM multi-spectral image to extract patterns related to iron stained alteration and hydroxyl alteration of mineralization form.Geological data are integrated with the results of remote sensing image processing to divide prospective districts and delineate prospecting targets.
