Rare Earth Element Concentrations in Mafics from the Kizil Dağ Ophiolite (Hatay, Turkey)

DELALOYE, Michel, et al.

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.
