Large Field Of Qinghai Province Gold Field Of Remote Sensing Geological Characteristics And Prospecting Significance

With the continuous development and progress of remote sensing technology, at the same time due to itself the advantages of remote sensing technology, that is intuitive, efficient and fast, especially in a relatively poor field work environment, remote sensing technology not only avoid suffering the adverse impact of environmental, also do a lot of savings of human and material resources, therefore, more and more extensive application of remote sensing technology in the prediction of geology and mineral resources.This article is in the research area that is the main mining area of the Dachang gold mine in Qinghai Province, using remote sensing technology focus of the study area of the mineralization and alteration and tectonic interpretation and extraction, the work is mainly through visual interpretation, on the basis of collected remote sensing images of the four King of the study area, by best band of the synthesis of false color remote sensing images, geometric correction, image fusion, spectral enhancement, the promoter region was cut, finally get a743-band Synthetic false color remote sensing image, two different band-op map. On this basis, by synthetic band operation plan, emphasis on the study area-specific silicification, pyrite and chlorite mineralization and alteration of information and structure information, at the same time, create a unique interpretation of the study area signs, through visual interpretation., interpret the outcome of the study area alteration in Figure1,which Contains105alteration information.and constructed to interpret the results of Figure1.Through the above work, on the basis of interpreted the alteration and structural characteristics of the study area, select the degree of exploration of the study area is relatively mature deposits, such as Dachang gold deposit, Jiageilongwa gold deposit, Zhajiatongna gold deposit, authentication, compared to results of remote sensing interpretation, after field verification and comparison of typical deposit, further finishing, alteration and structural information of the remote sensing interpretation in the study area.Last, alteration results map and constructed to interpret the results of Fig. and collected geochemical anomaly map in the study area with prospective, nested, by Studing area to verify the deposit as a reference, with geological software to registrate and correcte multi-source information, then, comprehensive analysis of the nested graph, explore the gold mineralization geological conditions in the study area, and delineate five metallogenic prognosis areas.
