Abstract

Post-collisional magmatism in western Anatolia produced several granitic bodies represented by shallow level intrusions. In this study, we present field, geochronology and geothermo-barometry results of the Solarya Pluton (SP, NW Turkey) in order to better understand its emplacement into the different levels of the crust. The SP consists of three main plutonic members showing different textural properties; the northern part of the plutonic body is represented by K-feldspar megacrystalline granodiorite (KFMG) with distinct porphyritic texture and southern part is made up of microgranite-granodiorite (MGG) displaying microgranular texture whereas haplogranite, which displays graphic/granophyric textures, is represented by a thin aureole between the SP and basement rocks.
