The Middle Eocene Toveireh plutonic body is located in the western margin of the Central-East Iranian Microcontinent (CEIM). This plutonic body consists of granodiorite, syenogranite, and monzogranite compositions. Granodiorite is the most predominant rock unit, which is composed of quartz, plagioclase, K-feldspar, hornblende, and biotite main mineral phases. The Toveireh pluton is metaluminous to weakly peraluminous (A/CNK = 0.85-1.04) and shows a calc-alkaline I-type affinity. Primitive mantle-normalized spidergrams show enrichment of large ion lithophile elements (Rb, Ba, Th, U) and light rare earth elements (REEs) (La/YbN = 6.8-8.24), as well as depletion of high-field strength elements (Nb, Ta, Ti, P). …

Turkish Journal of Earth Sciences
In the southeastern part of the Jebal-E-Barez Oligocene granitoids (Kerman province, Iran), there are numerous mafic dikes and this work attempts to investigate the petrological, geochemical and mineral chemistry of these dikes. The dikes clearly follow faults which trend mainly N50-70W and N20-40W. Their thicknesses vary from 1 cm to 3 m and their contacts with the host granitic rocks are sharp without any extensive contact metamorphism which may be due to the lack of magmatic fluids. The Jebal-E-Barez mafic dikes contain plagioclase, clinopyroxene and amphibole as major minerals and overall show porphyritic texture, but intergranular, ophitic and subophitic textures …
