The Late Triassic shales sequence of Ispartacay Formation in the Antalya Nappes, Western Taurids, Turkey do not show any trace element enrichment. But trace elements values of shales from the Ispartacay formation are broadly comparable with those of the average upper continental crust (UC). While there were a slightly enrichments in Ni, V, Bi, Cs, Cu, Zn, Co, Hf, Ga, Rb and Th. Ba, Nb, W, Sn, Sr, Mo, Ta, and Cd elements are slightly depleted in Ispartacay shales according to those of UC. Be, U, Zr, Pb values are not observed any change. Organic carbon content of the shales is between 0.18 and 0.96 % in formation. The shales do not show metal/TOC correlation. 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-Eval data. The organic matter is highly oxidized, decomposed and reworked. |
