[PDF][PDF] Microscopic and Diffractometric Studies Inferred from Skarn Zonations Between the Keban Metamorphites and Elazığ Magmatites, Around Elazığ.
In this study, characteristics of skarn rocks and associated ore minerals that are developed
along intrusive contacts between Upper Cretaceous Elazığ plutonic rocks (granite,
granodiorite, tonalite, diorite, gabbro) and Permo-Triassic Keban metamorphites exposed at
four different locations at 30 km northwest of Elazığ were studied. Skarn rocks observed as

Abstract
In this study, characteristics of skarn rocks and associated ore minerals that are developed along intrusive contacts between Upper Cretaceous Elazığ plutonic rocks (granite, granodiorite, tonalite, diorite, gabbro) and Permo-Triassic Keban metamorphites exposed at four different locations at 30 km northwest of Elazığ were studied. Skarn rocks observed as endo and exoskarns are composed of andradite and grossular-rich garnet; pyroxene (diopside, hedenbergite, pigeonite), amphibole (hornblende and tremolite/actinolite), epidote, quartz and sphene. On the basis of calcic and dolomitic character of wall rocks, a skarn zoning from bedrock to wall rock was identified. This zoning is associated with a disseminated ore mineral assemblage of magnetite, hematite, pyrite, chalcopyrite, specularite, ilmenite, pyrrhotite and covelline/chalcosine.
