Çizgisellikler Yardımı ile Tektonik ve Volkanik Yapıların Belirlenmesi: Çan-Etili (Çanakkale) Linyit Havzası Örneği

Abstract: In this study, the aim is to determine the volcanic and tectonic structures developed in the “Çan-EtiliLignite basin” with the aid of satellite images. The Çan-Etili lignite basin consists of Oligocene-Early Miocenevolcanics (Çan Volcanics) overlying early-Middle Miocene lignite-bearing stream and lake sediments (Çan formation)occurring above an unconformity. In order to complete this study, two different satellite images (ASTER and ALOSPALSAR) and a digital elevation model (DEM) of the region were used. Multispectral optical remote sensing dataprovide information about material composition, while radar data reflect surface topography and morphology better.During mapping of lineaments on satellite images, in addition to visual assessment, image processing techniqueswere used. A variety of orientation filters were applied to ASTER satellite images for lineament mapping. Thelineaments on PALSAR images were determined with visual methods.Using DEM data along with ASTER and PALSAR satellite images for the study area, lineaments were mapped. Theresults were shown that a significant portion of the lineaments had NE-SW strike. This orientation coincides with theNE-SW striking Çan-Etili fault. Additionally, some curved linear structures were obtained from satellite images andare interpreted to be associated with caldera development.
