Study On Geology And Geochemistry Characteristics Of Pingguo Raw Bauxite And Metallogenic Environment In Guangxi

The research on Guangxi Pingguo bauxite deposit was rarely associated with original ore, the research on original ore mostly maintain in the general macro geological characteristics level, To carry out the research on the bauxite ore and geochemistry information excavating of bauxite ore will provide an effective evidence for original ore ore-forming model.This study base on the project "The investigation of geological information extraction technology in the bauxite ore Prediction" , The author carry out the research on bauxite ore composition,structure and construction, geochemical characteristics and space distribution constraints by using X-ray diffraction, Microscopic identification, ICP-MS analysis and so on, and present some new understanding as follow:(1)Basing on X-ray diffraction and rock-mineral analysis under the microscope, the author determines the main ore's composition of original mineral mines. By using mineral composition and structure of the ore indication to the environment, this paper initially present the Al-rich layer formed environment and the ore deposit lies in the edge of continent.(2) Observing the ore structural in different mining area and distribution, analyzing the spatial variation pattern, and combing the mineral composition. The author shows the initial awareness ancient geographical environment pattern.(3)Through analyzing the REE,Pb isotope of bauxite,shale,limestone, the author think the material source is not only come from limestone, but other sedimentary rock,igneous rock, and indicate that material sources of the mining area in TaiPing and NaDou are different ,and trace the differences of the ancient landscape pattern.In summary, this paper attempt innovatively to determine the ore composition,structure and construction, geochemical trace original ore-forming environment, ore material sources distribution, and achieved their new viewpoints.
