摘　　要：彭泽县李家山钒矿矿体主要赋存于底寒武统荷塘组地层中,含矿岩石主要为碳质页岩、硅质页岩、含碳硅质岩。三条钒矿体严格受层位控制,呈层状、似层状产出。钒主要赋存在含钒云母类矿物中(伊利水云母),其次赋存于氧化铁、高岭土中。含矿岩系物质来源主要为陆源碎屑,沉积过程中有热水沉积及生物沉积作用的参与。The Lijiashan vanadium ore body in Pengze County mainly exists in the Hetang Formation of the Lower Cambrian.The ore-bearing rocks are mainly carbonaceous shale,siliceous shale,carbonaceous siliceous rock.The three vanadium ore bodies are strictly controlled by the horizon.The ore bodies are layered and consistent with the formation of the formation.Vanadium is mainly present in vanadium-containing mica minerals(erie water mica),followed by iron oxide and kaolin.Through the analysis of major elements,the source of ore-bearing rock series are mainly terrigenous clastics,and hot water deposition and biodeposition are involved in the sedimentation process.
