| Abstract: | Zhangyuan mafic rocks of NE-SW trend are distributed along the Yaoli-Zhangyuan-Jiangtan line in the northern slope of Zhanggong Mountain,between Anhui and Jiangxi provinces.They occur as structural shivers and fragments in flysch matrix textured by Neoproterozoic volcano-fine clastic rocks of continental margin,and overall display characteristics of tectonic melange belt.Mafic fragments include altered pillow-block basic lava,gabbro,dolerite,etc,which were concomitant in space since the Neoproterozoic.By an... |
