| Abstract: | The orebody of Xujie graphite deposit in Muoding,Yunnan is mostly bedded,stratoid in Pre-SinianJulin Group Pudeng Formation Member 2 Bed 3(Ptp2-3).The orebody occurrence is consistent basically to that of the strata.The ore commercial type is the fine scaly crystalline graphite deposit,belonging to the regional(sedimentary)metamorphic deposit in genesis.The main prospecting criteria are strata horizon and specific metamorphic mineral assemblage. |
