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 the metamorphites 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.
