| Abstract:Based on analysis of geological background and typical deposits in the Shangri鄄la area, this study focuses on the intermediate鄄acid intrusive
bodies which are related to porphyry mineralization郾In conjunction with data of gravity anomalies, magnetic anomalies, geochemistry and remote sensing郾,
as well as tectonic interpretation and geochemical anomalies from stream sediment survey and placer mineral anomalies in catchment basins, 45 target areas
for porphyry polymetallic copper deposits have been delineated郾This work has used the areal productivity method to estimate potential resources for these
areas and made a comparison with those target areas which were delineated by the weighted evidence model郾From a viewpoint of quantitative analysis, this
study concludes that the Shangri鄄la area is a prospective area with great potential for exploration郾It will provide scientific basis for mineral exploration and
further prospecting deployment郾 |
