The Pyrometasomatic Formations and Associated Fe-Ti Mineralizations at The North of Elazığ

Abstract: Permo - Triassic Keban Metamorphites outcrop at the North of Elazığ. The plutonics of Yüksekova Complex intruded in to themetamorphites during Late Cretaceous and caused formations of skarn zones and related Fe-Ti mineralizations along the contacts.Endoskarn formations exhibite various mineral assemblages; pyroxene (ferrosalite - hedenbergite) - garnet, pyroxene (fassaite)- skapolite and epidote - garnet. Mineral assemblages of exoskarn formations are garnet (andradite), skapolite, pyroxene, epidote,sphene and magnetite.The mineralizations occur along the metamorphites - plutonics contact, in the pockets and fractures extending towards marble.The thickness of the mineralized bodies can reach up to 1 -15 m. The ore minerals are; magnetite, hematite, ilmenite, specular ite,limonite, geothite, pyrite, pyrrhotite, chalcopyrite, covellite - chalcocite, geikilite and pyrophanite.
