| Abstract: | The Fe ore body is in the member 2,4 of Jiangfeng cycle of Middle Proterozoic Damenglong Group.The ore-bearing rocks are the meta-intermidiate-basic lava,hornblende(actinolite)plagioclase granulite,diopside albite(plagioclase)granulite.The ore deposit can be divided into the upper(Ⅰ)and lower(Ⅱ)2 ore bed.The upper one is stable.There are 4 ore bodies in lower one,which is a composite ore deposit,The Fe is transported,agglomerated and metamorphosed in-situ.It is a typical metamorphosed volcanic hydropneumatic magnetite deposit. |
