The thesis of the study area geology, ore-field structure, combination of remote sensing technology to complete mineralized structure interpretation and information extraction, and propose a comprehensive analysis of prospect area.Jianglang dome tectonic gone through the early ductile compressive - shear deformation, gravity slip ductile deformation of late, the two were on the deformation of sub-copper mineralization from the contribution of the role of copper makes the early stages of ductile deformation, which must be enrichment, the formation of low grade disseminated, banded ore; the late stage of ductile deformation is the most important copper mineralization, the formation of the dense layer may block high-grade copper ore body.Based on the Jianglang dome tectonic of remote sensing images interpretation, linear structure of the mining area, circular structure, with block formation of remote sensing information extraction, interpretation of this linear structure for the study area and a total of 260 faults. After analysis, the main development region trending linear structure, and gradually from east to west over north longing. High value area into the North East to the banded distribution. High-density areas are mainly concentrated in the dome structure of the nuclear wave Jiang, Regional; area of interpretation of ring structures 18, interpretation of ring structures concentrated in the eastern part of the study area, northwestern, central and southern regions, while these areas are linear structure and development area, and with the known deposits have a good spatial correlation.Through utilizes the main component analytic method and the threshold unusual analytic method, exceptionally divides the mining area remote sensing alteration for the hydroxyl, the iron dyes first-level, second-level, third-level exceptionally grades. The hydroxyl and the iron dye the alteration information mainly to concentrate in the research area eastern area, the western area are quite rare. Especially in the research area's southeast to the region, both has the strong performance, this region is also in the five copper mine locus, obviously between the alteration and the ore deposit has some kind of relation, may take the clue which further prospects to use. In the research area northwest and the north-west region, the region ring-like closure phenomenon is more obvious, simultaneously is following many issue of linearity tectonic element, has formed the quite bright geotectonic phenomenon, similarly in this region also has present already the copper mine which verifies, obviously between the lineation and the ring-like interpretation and the ore deposit origin also have the relation. Based on the linear structure interpretation, the ring structure interpretation as well as the stratum remote sensing information's interpretation, gathers the hydroxyl, the iron to dye exceptionally grades, this research gain's remote sensing interpretation information, the union geology information carries on the generalized analysis, forecast that two sheds, the Poris cocos mountain, the bamboo grove bay - small villages, the Tibetan national minority village - submarine trench, mill ditch - Jiang Langgou, Shi Gequ the altogether 6 regions for the prospecting prospect area, has made the beneficial attempt for the next stage prospecting work's development. In this research to instructs the five copper mine region and the periphery prospecting has the exploration significance, to the periphery long-barrelled gun, treads the card, nucleus mixed rock masses and so on Si dome prospect area to have the good enlightenment exactly.
