Özet:

 


The study area is situated between Hınıs-Tekman and Karayazı southeast of Erzurum. The aim of
this study was to investigate some geological characteristics of the region. The rock units constituting the lowermost
sections of the study area consist of alternating gneiss, amphibolite, schist and marble, from bottom to top,
are exposed beneath the ophiolitic complex, as a tectonic window. The ophiolitic complex consists essentially of
diabase, gabbro, and locally of serpentinite and peridotite. The acidic intrusions cut both the metamorphics and
ophiolitic complex. The rocks ranging from Maestrichtian to Pliocene in age are made up of regular alternations
of transgressive and regressive sequences, and rest upon the older rocks, unconformably. The study area became
a piece of land during the Middle(?) — Upper Miocene. The Oligocene sequence of the sedimentary cover contains
thin intercalations of andesitic basalt. In the Miocene-Pliocene sequence of the cover, firstly, volcanic rocks
varying from dacite to andesite in composition, and then, in turn, andesitic basalt and basaltic pyroclastic rocks
and lavas took place. Overthrusts which are of pre-Maestrichtian and Late Eocene age were also defined in the
study area. Along the Late Eocene overthrusts the ophiolitic complex has thrusted over the Eocene rocks which
are situated to the south of the complex. Parallel and oblique fault zones which have NW-SE striking right lateralslips
and NE-SW striking left lateral-slips were developed, as well as approximately E-W trending folds and
overthrusts under the control of compressional tectonic regime, during the Late and post-Miocene. In addition,
some other structures have been also developed in the Plio-Quaternary formations lying within both of two fault
zones, by the effects of approximately E-W trending compressional forces.
