| Abstract: | The Matigou crystalline graphite deposit in Ji an City,Jilin Province is located in the area of Matigou,Caiyuan Township,Ji an City,Jilin Province.In this paper,the authors studied the geological characteristics and genesis of the deposit such as strata,structure,magmatic rock and so on.It is believed that the corresponding deposits,such as crystalline graphite,boron iron formation,phosphorous diopside formation and uranium rare earth formation,which occur in the Huangchagou Formation of the Lower Proterozoic Ji an Group,belong to stratabound deposits of submarine volcanic eruption,sedimentary metamorphism and magmatic hydrothermal process.The genetic type of Matigou deposit is sedimentary metamorphic crystal graphite deposit.The prospecting criteria of crystalline graphite ore in this area are summarized. |
