Analysis Of Ore Controlling Structure Surface Of Mengyaa Pb-Zn Deposit In Tibet

The research of ore controlling structure is the key point of the research of modern deformation and mineralization.On the basis of understand the geological and mineral resources of the mining area and mining area fully,and understand the basic geological conditions of the area and the mining area fully.According to the project related work,under the guidance of the theory of tectonic mineralization,Completed the regional route geological survey?mining structure mapping?analysis of ore body characteristics and analysis of mining engineering.Then,draw the line profile,mine tunnel sketch and ore prospecting line section,middle plane projection analysis,Preliminary determination of the regional and mining area deformation framework,deformation style and style combination,To clarify the ore controlling structure of the mining area and analyze the characteristics of each type of ore controlling structure,the following conclusions are drawn:Mengyaa Pb-Zn deposit of regional deformation of lattice frame is mainly by Jiali arc basin system,the ancient Tanggu-baga anticlinorium and loose multi nappe fan North fan body,a leaf Ba superimposed back arc basin,and the mengya Pb-Zn deposit is located in the northern part of Jiali arc basin system,the southern pine multi nappe fan Bei fan body and loose multi nappe fan anticline in the southern North fan body reverse thrust nappe and the formation of the ancient Tanggu-baga complex.Mengya Pb-Zn deposit is located in the south of ancient Tanggu-baga anticlinorium,forming a a series of multistage isoclinal "Z" type subordinate fold,and uneven distribution of axial joint deformation style combination.A full discussion of the mengya Pb-Zn deposit,ore control structure surface for the ancient Tanggu-baga complex anticline in the southern "Z" type subordinate fold axis of joint surface folds are related to joint system and the level of structure.The above results are in accordance with the practice of Mongolia and Asia,the deposit,the project has a certain support,the company has a certain guiding significance for exploration.
