Marmara Denizi`nin kuzeydoğusundan (Fenerbahçe-Pendik) alınan yüzey ve karot örneklerinin minerolojik ve petrografik incelenmesi

Abstract

IV ABSTRACT This study was carried out in the northeast of Marmara Sea (between Fenerbahçe- Pendik) in an attempt to determine mineralogical distribution by surface and core samples. Clay minerals are major constituents of materials deposited in the area studied. These unconsolidated sediments contain Pelecypoda and Gastropoda fossils in many level. Kocaeli Peninsula near study area can be a source area for the sediments deposited in the study area. In Kocaeli peninsula, there is a secuence which begins with Paleozoic upto actual. During laboratory studies whole rock mineralogical analyses using XRD techniques were carried on surface and core samples. As a result of this studies, clay, quartz, dolomite, calcite, feldspar and muscovite minerals were determined. Clay minerals are very abundant in samples. By detailed clay fraction studies on sediments, smectite, illite, kaolinite and a little amount of chlorite minerals are determined. Some gravel samples collected from cores are investigated from their thin sections under polarized microscope. These gravels are described as phyllites and sandstones. There might be a fault, near 5, 6, 7' th locations. Because of a lot of fossils, and their size increase. These locations are also deeper than other locations and grain size of rocks are much bigger than other rocks.
