Mineralogical and Geochemical characteristics of "Khezr-Abad pluton" NW of Taft, Iran.

Khezr-Abad pluton is cropped out in North-West of Taft. This granitoid seems to be younger than the surrounding metamorphosed rocks, particularly the lower cretaceous limestones and probably is implaced during Oligo-Miocene. The most volumetric abundances of the igneous rocks are: granodiorite, granite, quartzmonzo-diorite, quartz-diorite, and in a lesser amount tonalite, quartz-syenite and syenite. All granitoid rocks show Ba, K, Rb enrichment, and Nb, Sr, Ti depletion. From the economical potential point of view, mineralization of marble, Fe-Cu-Pb-Zn skarn and non-metalic minerals such as kaolinite are considerable. Geothermobarometry of rock forming minerals of this pluton indicates temperature of  810- 985 ˚C and pressures of  2.43 – 6.2 kilobars (kbar).
