Iron mineralization and associated skarn development around southern contact of the Egrigoz pluton (northern Menderes Massif-Turkey)

Abstract

The Egrigoz pluton is located in the northern portion of the Menderes Massif, which is the largest known metamorphic core complex that is also characterized by large-scale extension. Kalkan and Karaagil skarn deposits are located on the southern border of the Egrigoz Pluton, whereas Katrandag mineralization developed along the roof pendant. Skarnization in these three areas is associated with the peraluminous, I-type, talc-alkaline, high-K calc-alkaline Egrigoz Pluton. Geochemical characteristics of the pluton indicate that it was generated in a continental arc setting. Kalkan, Karaagil, and Katrandag skarns are hosted in marble bands in two-mica gneiss of the Kalkan Formation, a locally dolomitic and clay-bearing limestone of the Arikaya Formation and locally dolomitised limestone of the Balikbasi Formation, respectively.
