The Manpai Tungsten Deposit Genesis And Prospecting Potential Evaluation In The Fourth Special Administrative Region,Myanmar

The Manpai tungsten deposit is a no tin tungsten deposit found in recent years,the Fourth Special Administrative Region,Myanmar.This dissertation topics closely with tutor professor Mingyou He undertakes the Burma’s fourth dc line of tungsten ore district geology exploration "project,select the deposit genesis and prospecting potential evaluation on dissertation research.Research content including: metallogenic geological structure background,tungsten deposit mineralization features and the causes of tungsten deposit and prospecting potential evaluation.For the research content,the use of structural geology,stratigraphy,deposits,petrological and geochemical studies the theory and methods of the ore-forming geological tectonic background,in-situ tests by X-ray fluorescence spectrometer analysis of rock mineral elements,and the use of ICP-engage and ICP-MS testing analysis of the rock ore chemical composition,trace and rare earth elements.According to the results of data processing,combined with geological research results has carried on the comprehensive study.By studying the following conclusions:1.Within the mining area is formed by the crust remelting granite in the acid,calcium alkaline magma along the deep fault belt into form.The formation of the granite rock mass containing tungsten rock mass.2.Granite rock mass with good shielding effect in the overlying strata and the block late magmatic crystallization differentiation gas liquid and the important role of hydrothermal escape upwards.Therefore,it makes the late magmatic crystallization differentiation to large-scale gas liquid gathered on the top of the rock mass,and a massive greisenization.In the process of greisenization happen,tungsten got preliminary enrichment,even in the strong body parts greisenization form tungsten mineralization.3.The mining area of the fracture structure formed by the strong fault activities,both shaped ore-forming environment,orebody of space geometry,and cause the height of the rock broken,to form tectonic cataclastic rock construction.Tectonic cataclastic rock has a great deal of porosity and permeability,very conducive to the ore-bearing hydrothermal flow,diffusion and permeability.4.When magma gas liquid into the ore-bearing hydrothermal,ore-bearing hydrothermal with characteristics of high temperature and high pressure,the secondary fracture structure along the flow,diffusion and permeability.In the ore-bearing hydrothermal into favorable metallogenic environment,large-scale mineralization,forming industrial tungsten deposit.5.The results show that the mining prospecting potential in the situation of the west ore belt,belt and the east mine area have good ore-forming geological conditions,ore-controlling tectonic belt development,containing ore hydrothermal process strongly,veins numerous and has a certain scale,ore grade is high,quality is good.Two zones are potentially prospecting potential,develop is expected to boost line of tungsten deposit industrial reserves.
