Özet

In the Ananias-Akseki platform (SW Turkey), the Triassic Kastmlar Formation consists of bituminous shale and bedded reefal limestones. Detailed data from thick Triassic sediments (Kasunlar Formation) made it possible to construct an organic facies framework using different zonations. Organic matter is composed predominantly of woody material, with a minor contribution of planty and amorphous material. Kerogen in the deposits is type III, as indicated by organic petrographic observations and Rock Eva] data. Total organic carbon (TOC) values are generally between 0.02 and 0.96%, but reach 3.78% in the formation. Tau, values vary between 284 and 454 degrees C, confirming the increase in maturation trends indicated by vitrinite reflectance data. Organic facies type D was identified in the investigated units. Organic facies D is related to shale and carbonate lithofacies. This facies is characterized by average values of HI around 19 (equivalent to type III kerogene), TOC around 0.51%, and an average of S, of 0.04 mg HC/g of rock. Organic facies D is nongenerative; the organic matter is highly oxidized, decomposed and reworked. (C) 2014 The Authors. Published by Elsevier Ltd.
