Structural Analysis And Deep Geological Studies In Huize Jinhong Area

Based on the collection of a large number of regional geological data and deep geological data in Huize Qilinchang Lead and Zinc Mine; combined with geological survey and geophysical data,;using geological analogy method, this essay analyse the deep geological information of the study area and forecast the concealed ore body, achieve the following results and understandings:(1)The study area lies to southwestern margin of the Yangtze; east of Sichuan-Yunnan-Guizhou block.its center is 6.2km far to the south of Huize Qilinchang Lead and Zinc Mine.The similarities between these two places of regional geology, mineralization conditions, lays the core idea of this essay.(2) through detailed field geological work,this essay identify stratigraphy and structure (folds, faults and Joint) of the study area. Take resolve tectonics as guiding ideology, through counting and analysing structure of study area structure, and making stereographic projection., Analytic structure of the study area,;basically determin the constructed Endogenous Development System of the study area; Provide a strong basis for the deep structure of the study area; At the same time strengthen the basis of the tectonic metallogenic prediction.(3) explore and summarize the deep geological information in Huize Qilinchang Lead and Zinc Mine systematically:(1) stratigraphic thickness is relatively stable from the surface to the deep,rock formations is steep; (2) The structure density decreases gradually from the shallow to the deep; scale is gradually increased, with the characteristics of multi-phase activity; (3) distribution of lead-zinc ore body is related closely to.stratigraphy and structure.(4) Take deep geological data analysis in Huize Qilinchang Lead and Zinc Mine as a reference, combined with the geophysical data interpretation results and geological analogy method:inferred deep geological information of the study area, ? the main ore-bearing horizon-- C1b is 80-110m thick, whose angle is 60-80°; ? NE faults is developed 600m underground? delineated four host rock ?1??2and ?1??2(5) Using integrated information prospecting methods, establish the deep geological-geophysical-geochemical prospecting model,forecast the concealed ore body in the study area, and provide the optimal solution of drilling verification.
