Determination of Tectonic and Volcanic Structures with the aid of Lineaments: Example from ？an-Etili (Canakkale) Lignite Basin

In this study, the aim is to determine the volcanic and tectonic structures developed in the “？an-Etili Lignite basin” with the aid of satellite images. The ？an-Etili lignite basin consists of Oligocene-Early Miocene volcanics (？an Volcanics) overlying early-Middle Miocene lignite-bearing stream and lake sediments (？an formation) occurring above an unconformity. In order to complete this study, two different satellite images (ASTER and ALOS-PALSAR) and a digital elevation model (DEM) of the region were used. Multispectral optical remote sensing data provide 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 techniques were used. A variety of orientation filters were applied to ASTER satellite images for lineament mapping. The lineaments 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. The results were shown that a significant portion of the lineaments had NE-SW strike. This orientation coincides with the NE-SW striking ？an-Etili fault. Additionally, some curved linear structures were obtained from satellite images and are interpreted to be associated with caldera development
