Title: Geological and Geochemical Characteristics and Genesis of the Sn-Fe Polymetallic Deposit in Taliabu Island,Indonesia
Abstract: A large-size Sn-Fe polymetallic deposit,with more than one hundred million tons of iron reserves whose average grade(total Fe) is above 50%,has been recently discovered in Taliabu Island,Indonesia.Skarn and ore-magma are the main genetic types of the ore deposit,with the existence of hydrothermal type.These genetic types constitute a complete metallogenic system.The Indo-Chinese monzogranite derived from crustal partial melting magma is the main metallogenic material source and ore-control factor.Through high-degree evolution,the magma produced Fe-rich ore-magma injection and subsequently formed ore bodies,which mainly occurred in drastic variation places along rock mass boundary,soft and hard rock boundary in the contact zone between granite and Carboniferous strata.Skarn type iron ore was formed in the contact zone between Carboniferous(dolomitic) marble,calciferous metasandstone and granite.The ore deposit belonged to Eastern Australia metallogenic belt during its formation,and then moved to Southeast Asia metallogenic belt by Himalayan movement.
