| Abstract: | The Dazhuangzi gold deposit lies in Pingdu City,Shandong Province.Tectonically,it is located in the southwestern corner of Jiaobei terrain and on the northern margin of the Mesozoic Jiaolai basin;to the west,it is adjacent to the Yishu fault zone.The ore bodies,which are hosted in metamorphic rocks of Paleoproterozoic Jingshan Group,can be divided into two types,namely the altered cataclasite or mylonite type and the quartz vein type.Microthermometric investigation reveals that gold precipitation occurs at ... |
