Geological characteristics and genesis of the Xialei Mn deposit in Daxin County,Guangxi

JIN Xi;CHEN Xianfeng;Development Research Center of the China Geological Survey;Geological Team No.4 of Guangxi Zhuang Autonomous Region;  
The Xialei Mn deposit in Daxin County is the largest manganese deposit in China.The formation of the deposit is closely related to sedimentary basins,sedimentary formations,tectonic settings and hydrothermal activities.Base on the deeply analysis to the characteristics of rock assemblage,mineral characteristics,elemental geochemistry,stable isotopes and rare earth elements,especially the characteristics of typical mineral pyroxene,diopenite and so on,it shows that the important element for the formation of Xialei Mn deposit is closely related to the participation of abundant ore forming materials in submarine volcanic eruption activities,and the genesis of the deposit belongs to the hydrothermal exhalative sedimentary deposit.
