Intrusive masses of Taft area are out-cropped in south-west of Taft. These granitoid bodies seems to be younger than the surrunding metamorphosed rocks, particularly the lower cretaceous limestones, probably related to oligo- miocene ages. The most volumetric abundances of igneois rocks are: Granodiorite, Granite, Quartz Monzo- Diorite, Quartz- Diorite, and in a lesser amount: Tonalite, Quartz-Syenite and Syeinite.From geochemical point of view, The amount of SiO2, K2O and CaO contents, in different points of intrusive bodies are variable, and Ba, K, Rb enrichment, Nb, Sr, Ti depletion could be seen. Plot of results on Spider diagrams show this matter. The Granitic intrusives of Taft area are geochemically Itype granite. From economical potential point of view, Mineralization of Marbel, Skarn, Fe, Cu, Pb, Zn and non-metallic minerals such as kaolinite are considerable. Geothermobarometry of minerals of rocks, from metamorphic haloes of these masses indicates thermal conditions of 600-650 c and pressures 1.5-2 kb.
