Stratigraphy of the Munzur Mountains (Kemah-Iliç-Erzincan)

Abstract: The Munzur mountains, which reflect typically the geological peculiarities of the Taurides, are situated at the north-eastern endof this unit. In this study the subsequent formations have been distinguished from bottom to top: Munzur limestone (Liassic-EarlyCretaceous), Uluyamaç ophiolithe (Jurassic-Cretaceous), Eric melange (Late Campanian-Early Cretaceous), Yakuplu plutone (Paleocene), Haslar andesite (Pat eocene), Dedek formation (Eocene), Kemah formation (Miocene).The uppermost levels of the Munzur limestone, deposited on an isolated carbonate platform, include biomicrits with Globotruncana. These biomicrits were formed as a conscnquence of the breaking and sudden collopse of the platform. The Uluyamaç ophiolithe that does not manifest a uniform sequence in the area, consists ofophiolithic rocks with a nontabular appearance. The Eric melange is made up of a chaotic mixture of rock blocks of different ages and fades in a pelagic matrix. Both of these lit hostr at graphicunits are in tectonic contact with each other and with the Munzur limestone. Both the I-type Yakuplu plutone, formed as a consenquence of partial melting of the subducting oceanic crust and of the mantel material, and Haslar andesite, crosscut all the rocks already present. The Dedek and Kemah formations unconformably overlay the other units.
