Spatial And Temporal Distribution And Prospecting Significance Of Pb-Zn Sedex Type On Marginal Basins Of Junggar-Alatau

There are a lot of SEDEX-type lead-zinc deposits in Kazakhstan, and many of them are large deposits. But SEDEX-type lead-zinc deposits are few on Xinjiang Bei-Tianshan, in which belong to the same tectonic unit with Balkhash-Junggar fold belt. Because of differences in minerals., quantity、scale about domestic and foreign, determines the necessity of "cross-border" comparative study of metallogenic belt. Thus, to a higher level of study abroad deposit as a model, and comparative analysis of the extent of research within the lower region, and reaches the importance of cross-border research.This paper chose Junggar-Alatau marginal basin as a research area on China-Kazakhstan, summed up the law system of mineralization foreign typical deposits and realize territory prospecting prediction purposes.Though collecting the basic geological data (data, maps, tables, etc.) which are predecessors summarized, and compare to analyze the differences with stratum on domestic and divide into several small prospects; Though the study of foreign mineralization typical deposit to sum metallogenic regularity, and then supplemented by remote sensing, syngenetic structure, ore stratigraphic column and geochemical data, and form spatial and temporal distribution of Pb-Zn SEDEX type. Finally, this rule will be applied to the small of prospects, and though ASTER remote sensing data, stream sediment geochemical data further reduces prospects in scope, reach target selection purposes.Comparative results of previous studies, this paper has the following two innovations:the first time in the study foreign area typical Pb-Zn SEDEX type for the model area, and reaches cross-border research; the first time within the domestic study area Pb-Zn SEDEX type target selection.The master’s degree thesis the following two meanings:study on mineralization law of foreign deposits in the same a metallogenic zoning and tectonic, with a strong guiding significance in mineral exploration and research work about domestic; taking into account the importance of Pb-Zn SEDEX-type and unity of the mine with mineral deposits and mineralization type, the master’s degree thesis research work, carried out for the respective series of cross-border work metallogenic belt with a typical exemplary.
