Abstract:

Mineral exploration has stridden forward a new era of application of comprehensive ore-forming information to systematically quantitative search for buried large and super-large ore deposits with help of sophisticated techniques. The sophisticated survey, including 3S( GPS, GIS, RS) technology, dating technology and information processing techniques supply new support for mineral exploration. Based on the multi-information of porphyry Cu deposit in the Yulong area of eastern Tibiet, the forming and preservation of Cu deposit can be quantitatively evaluated through DEM (Digital Elevation Model) data processing and three dimensional simulation with 3S. The research result shows that ancient geography and ancient climate characters are favor to estimate the origination time of porphyry denudation; the denudation speed and the forming age of deposit are the important parameters to research deposit scale and conservation environment; the quantitative data of stratum, rock, structure and DEM are the important factors to evaluate ore-forming pattern.
