Major and trace element enrichment in Kızıldere formation (Arsuz Hatay)

Abstract

The study area is in the Arsuz - HATAY region and the geochemical properties and deposition environment of the claystones in the Kızıldere Formation (Middle - Upper Miocene) were investigated in this study. Kızıldere Formation, which is common in Arsuz and İskenderun (Hatay) regions, has both bedrock and reservoir rock characteristics. It generally consists of a sequence of medium bedded sandstones and thin to medium bedded claystones. The average concentrations of major and trace elements in the samples taken from ten different points of the Arsuz region were determined (V-1180.65 ppm, Ni-219.83 ppm, Cr-149.26 ppm, Co-19.45 ppm, Cu-22.63 ppm, Rb-42.96 ppm, As-8.40 ppm, Zn-54.47 ppm, Sb- 0.61 ppm, Mo-1.28 ppm, Cd - (- 0.71) ppm, Pb- 5.68 ppm, U-1, It is 35 ppm, Ba 171.15 ppm, Li-24.64 ppm, Cs-3.06 ppm, S-325.48 ppm). V / Ni, Ni / Co, V (V + Ni), V / Cr, (Cu / Mo) / Zn ratios in claystones and increases in concentrations in trace elements (e.g. V, U, Ni) indicates that it precipitated in the marine-anoxic environment. In addition, in the distribution mapping drawn according to the trace elements Ni-U-Cu-Zn in the region, the paleo-environment changes with organic matter conservation were determined.
