Lignitic Sandstones" of The Trakya Basin

Abstract

Uppermost Eocene - Lowermost Miocene Yenimuhacir Group of the Trakya Basin consists of clastic sediments representing deltaic facies associations with a total thickness of 3500 meters. Major facies associations of prodelta, delta front and delta plain can be differentiated both in the field and in the oil exploration wells, and they are named as Mezardere, Osmancık and Danişmen formations respectively. The unit described as "lignitic sandstones" in early studies, represents delta front and delta plain environments of the system forming the Yenimuhacir Group. They are the equivalent of Osmancık and Danişmen formations described in this paper.
