Abstract: The bulk composition (major and trace elements) and the composition of minerals in peridotites of the Ortaca area, south-western Turkey, have been investigated to understand the processes controlling lithological and compositional variations in the dismembered mantle section, containing clinopyroxene-bearing harzburgite, harzburgite and dunite. The Ortaca peridotites vary from almost fertile clinopyroxene-bearing harzburgite (1.92-2.42 wt\% Al2O3, 2.00-2.64\% CaO) with a lower Cr# of the spinel phase (
