The Comparative Study Of Granitic Rocks Petrological Characteristic And Metallogenic In BaoShan,HuangShaping And Shizhuyuan

The Nanling region and its neighboring areas developed granites of different ages and granites of Yanshan time is closely related to the abundant mineral in the region,metal mines known mainly in the granites of Yanshan time or around.The study areas in major metal mine of Baoshan,Shizhuyuan,Huangshaping,and comparative study the time of Yanshan granitoids its petrology,geochemistry,ore-bearing granitoids genetic types,tectonic environment,exploring granite contributioning to the different of metal mineralization.Three different rock types within the study area,using QAP and petrographic observation:Baoshan is mainly granodiorite porphyry;Huangshaping is mainly granitic porphyry;Shizhuyuan is mainly peraluminous biotite granite/granite porphyry.A/CNK-A/NK illustration to determine the lithology aluminum saturation level.Baoshan granodiorite porphyry is metaluminous series;Huangshaping granitic porphyry is metaluminous-peraluminous series;Shizhuyuan peraluminous biotite granite/granite porphyry is peraluminous series.The differences of rock type,aluminum saturation index,to explore the size and type of deposit and provided the basis for petrological aspects.According to the sample rare earth elements,trace elements and through the standardization of data,the distribution patterns of rare earth elements and trace elements spider diagrams can be maked.Scatter made by different trace elements,determine granitic rocks of the areas of Baoshan,Huangshaping and Shizhuyuan genetic mechanism of granitic rocks,source rocks,tectonic environment,for making judgments about the study of different mineralization.From a source of minerals,redox,fractional crystallization,rock alteration,tectonic environment to discuss different types of the Baoshan Cu-Mo-Au-W deposits,Huangshaping Pb-Zn-Cu deposits,Shizhuyuan W-Sn-Mo-Bi deposits.
