On the geochronology by K-Ar method of the Rize pluton in the region of Güneyce-Ikizdere, Eastern Pontids, Turkey

TANER, Mehmet Fevzi, DELALOYE, Michel, VUAGNAT, Marc

Abstract

The Rize Pluton is situated in the Eastern Pontids. The Güneyce-Ikizdere area consist mainly of plutonic rocks of calc-alkaline composition and of Cretaceous volcanic and volcaniclastic formations. Potassium-argon age determinations were carried out on mineral concentrates as well as on whole rocks. An isochrone is calculated for samples from Maki Deresi-Ikizdere area (71 m.y.) and a second one for samples from Cimilbasköy (42 m.y.). The obtained results lead to the conclusion that the emplacement history is quite complex and lasted a long period. The intrusion of the Rize pluton was synorogenic and took place in the main phase during the Laramide tectonic orogeny.
