Özet

Eocene bituminous shales within the Camalan Formation of Paleocene-Eocene aged Kizilcay Group exposing around Tekirler (Nallihan, Ankara), central Anatolia, were deposited under oxic and suboxic redox conditions and have Corg values in the range of 2.37 to 12.42 wt% (average 6.32 wt%). Samples are represented by Type-I kerogen and their maturity level is immature-early mature. Eocene bituminous shales are enriched in some major and trace elements, such as Ca, Mg, Si, Na, K, V, Ni, U, Th, P, S, Mo, Cu, Zn, Cr, Co, Pb, Au, Ag, As, Re, La, Ce, Pr, Nd, Li, Sm, and Y. Paleoredox indicators (e.g., V/(V+Ni), Ni/Co, U/Th, V/Sc, Mo/Mn) yield that Eocene bituminous shales were mostly deposited oxic-suboxic conditions.
