Abstract :The basal part of the Hüdai Formation insert ignore into journalissuearticles values(Early Cambrian); in the Aydıncık insert ignore into journalissuearticles values(Mersin); area comprises red sandstone beds at different stratigraphic levels, showing ripple cross-lamination. These beds were deposited in the middle to lower part of an intertidal flat environment. Bedding-parallel reddening and its cyclic character suggest syn-sedimentary or early diagenetic red colouration in a marine environment. Both X-ray diffraction and petrographic analyses indicate that the red sandstones are composed of predominantly K-feldspar and quartz grains and an illite matrix. These are dominantly arkosic wacke. A small amount of hematite insert ignore into journalissuearticles values(
