Abstract

Within the scope of this paper, seismic reflection and bathymetry studies were carried out in theshallow marine area forming the westernmost part of the Tekirdağ Basin using the R/V SelenResearch Vessel within the MTA Marine Research Department. In the study area, ~ 500 km lengthbathymetry data and ~191 km shallow seismic profiles ( 41 lines) were collected. By means of thedata, tectonic structures and deformation textures of the North Anatolian Fault System (NAFS) inthe marine area of Gaziköy were examined. As a result of the processing and interpretation of theseismic sections, compression structures occurring due to the SW rotation of the NAFS in the studyarea, the morphology of the Ganos depression that formed as a result of faulting and also threedifferent stratigraphic units were distinguished. These units are separated from each other by distinctunconformity surfaces and each unit presents different deformation structures. One of the mostsignificant results obtained from the seismic data is that the unconformity surface that separates thecurrent sediments of the seafloor from the older units is represented by the overlapping structuresindicate sea level changes. It has been assessed that this situation occurred as a result of the erosionalprocess developed during sea level fall.

Özet

Bu çalışma kapsamında, MTA Deniz Araştırmaları Dairesi bünyesinde bulunan R/V Selen Araştırma Gemisi kullanılarak Tekirdağ Havzası’nın en batı kesimini oluşturan sığ denizel alanda 41 hat boyunca 191 km sığ sismik ve ~ 500 km uzunluğunda batimetri verisi toplanmıştır. Böylelikle, Kuzey Anadolu Fay Sistemi (KAFS)’nin Gaziköy güneyinde bulunan denizel alanda bulunan tektonik yapıları ve deformasyon dokuları incelenmiştir. Sismik hatların veri işlem çalışması ve yorumlanması sonucunda, çalışma alanı içinde KAFS’nin GB’ya dönmesine bağlı olarak ortaya çıkan sıkışma yapıları, faylanma sonucu oluşan Ganos çukurluğunun morfolojisi ve ayrıca üç farklı stratigrafik birim ayırt edilmiştir. Bu birimler birbirlerinden belirgin uyumsuzluk yüzeyleri ile ayrılmakta ve her katman farklı deformasyon yapıları sunmaktadır. Sismik verilerden elde edilen en önemli sonuçlardan biri de deniz tabanı güncel çökellerini yaşlı birimlerden ayıran uyumsuzluk yüzeyinin deniz seviyesi değişimlerine işaret eden aşmalı yapılar ile temsil edilmesidir. Bu durumun, deniz seviyesindeki düşüş döneminde gelişmiş erozyonal sürecin bir sonucu olarak ortaya çıktığı değerlendirilmiştir.
