STRUCTURAL CHARACTERISTICS OF KIRAZLI DISTRICT, ÇANAKKALE, TÜRKİYE

Abstract

The Biga Peninsula, which geologically evolved in relation with the the closure of the Tethyan oceans during pre-Cenozoic and subsequent syn-, post-collisional extensional tectonic regime throughout the Cenozoic located in the northwestern Türkiye. The Kirazlı district and and surrounding regional study area covers the central part of Biga Peninsula where Permo-Triassic Rhodope and Sakarya Zones sutured during closure of Paleo-Tethyan marginal seas along Intra-Pontide Suture (IPS). Neo-Tethyan northward subduction and closure, limit the Biga Peninsula from south along İzmir-Ankara-Erzincan Suture (IAES). Following syn- and post-collisional, slab break-off, slab roll-back events accompanied by crustal extension, metamorphism, core-complex formation, southward retreat of subduction front and resulted in generally southward younging magmatism. 
 Field observations showed that Kirazlı district was exampled both Rhodope and Sakarya basement rocks along its eastern sector those were covered by Oligocene volcanic sequence at the rest of district. Resultant Cenozoic structural architecture of post-collisional tectonic regime includes three and four predominant fault orientations respectively in regional and district scale study areas. Investigating the tectonic characteristics of these faults at both regional and district scales will be instrumental in unveiling the temporal and spatial relationships among Cenozoic structures. To achieve this goal, the study examines and discusses the tectonic properties associated with the identified predominant fault orientations.
