The Zargoli granodiorite is located in the northwest of Zahedan in Sistan suture zone. This granodiorite intruded a flysch-like unit at Oligocene and its SiO2 contents range from 62.4 to 66 wt. %. This gronodiorite is calc-alkaline, metaluminous and I-type. The Zargoli More
The Zargoli granodiorite is located in the northwest of Zahedan in Sistan suture zone. This granodiorite intruded a flysch-like unit at Oligocene and its SiO2 contents range from 62.4 to 66 wt. %. This gronodiorite is calc-alkaline, metaluminous and I-type. The Zargoli granodiorite shows negative anomaly of Ta, Ti, Nb, Eu and positive anomaly of Rb, Ce, La, Ba, Sr in spider diagrams suggesting that these rocks have been derived from the partial melting of lower crust. This magma was contaminated with flysh- type sediments during emplacement in Sistan suture zone. Discriminative diagrams indicate a volcanic arc (VAG) and active continental margin (ACM) tectono-magmatic setting for this pluton.
