Nasarawa Li deposit located at northeast rare metal belt in central Nigeria is one of the most important pegmatitic lithium deposit.Experimental study on sampling depth and grain size of soil sample collected in Nasarawa area is carried out to provide soil geochemical basis for prospecting pegmatitic Li de-posits in the Region.Vertical section sampling method is adopted and is selected represntative section to verify the method.The Experimental sampling depth is 30-50 cm and grain size-20～+60 mesh.Anomalies obtained are well corresponded with the burried ore bodies.The result shows that the method will be effective to prospect rare metal deposit in similar landscape.
