Abstract Abundances of rare earth elements (REE) from the mafic sequence of the Kizil Dagh - Hatay ophiolite have been measured by neutron activation technique for short lived isotopes. The results for twelve samples from the gabbroic part show a general REE pattern with a depletion in the light REE (LREE) indicating that these rocks were derived from a uniform LREE depleted asthenosphere source (Schilling, 1975) at a spreading zone. The REE abundances vary by a factor 6 to 10 between the cumulate gabbros from the ultramafic - transition zone and the high level microgabbros from screens in the dyke complex.
