Mineralization characteristics and exploration strategy of world-class Manono lithium deposit,democratic republic of Congo
摘要
Abstract
The Manono world-class lithium deposit in the Democratic Republic of Congo is located in the Kibaride Belt of central Africa.It belongs to LCT pegmatite-type lithium deposit and was famous due to the big tonnage and high grade.Based on the latest exploration result and systemic study of the geological characteristics and min-eralization,this article proposed that the zoning of Manono ore-bearing pegmatite is mainly along the dip direc-tion.From the top to the root,three zones were distinguished:the greisen pegmatite zone(top zone,Sn minera-lization dominant),the sodium feldspar-spodumene pegmatite zone(middle belt,main lithium mineralization zone)and the K-feldspar granite pegmatite zone(root zone,barren),so called"top Sn and below Li"mineraliza-tion structure.The formation of the Manono lithium deposit is attributed to the optimal combination of magma-structure-wall rocks.It is considered that"double-layer differentiation"of the lithium bearing G4 granitic magma play an important role.That is mean the crystallization differentiation of deep magma chambers and the liquid dif-ferentiation of shallow LCT magma chambers,is the key metallogenic mechanism for lithium enrichment.An use-ful Manono-style LCT pegmatite lithium deposit exploration strategy was concluded based on the discovery and exploration experience of the Manono deposit:Searching artisanal mining traces through remote sensing images,assessing the tin occurrence(artisanal mining sites),then using the"top Sn and below Li"model to find Li min-eralization,locate pegmatite belts(bodies)and ore controlling structure based on high resolution aeromagnetic da-ta,and conducting systematic geology exploration.There are many rare metal artisanal mining sites around Manono area,it is high potential to find Li mineralization.Using this Manono-style exploration strategy can help quickly to find and evaluate the exploration targets.关键词
