ABSTRACT: Structural textural and petrographical properties and paleocunent directions of the Miocene Karsan ti sandstones have been investigated within an area of 75 sq-km in. tie Karsanü. region (N of Âdâna) by means of detailed sedimentological logging and sedimentary petrological studies. The geological age of the Kanamı Formation has also been determined by microfossil dating as Upper Miocene. On `the basis of detailed geologic, micromineralogic and petrological studies. `The sedimentation model and paleogeographlcal reconstraction of the Kars anlı Formation in area investigated were reconstructed. As a result of these studies it has been postulated that the clastic sequence of Aie Karsantı Formation deposited in a shallow marine environment with two allocthonous coalbearing carbonate levels in the. lower - middle and middle- upper levels which formed tinder lagunar and/or fluviatile conditions. Results of these sedimantarv petrological studies revealed that detritus of the Karsanti arenites were derived from a. northernly basic-ultrabasics rich provenance, i.a. Taurusophi.oliti.que Subduction Complex, and. Karsanti stratigraphie sequence postulated as an arctrench gap related sedimentary unit.
