“…Middle Jurassic MBPC granitic rocks, Ahadnejad et al 2010). In this regard, just three cumulate 344 gabbros do display significant deviation from the other samples on crustal contamination.…”

“…1). Major progress has been made in recent years in unravelling the ages of these complexes by U-Pb zircon geochronology (e.g., Ahmadi-Khalaji et al, 2007, Shahbazi et al, 2010, Mahmoudi et al, 2011, Ahadnejad et al, 2011, Esna-Ashari et al, 2012, Alirezaei and Hassanzadeh, 2012. However, the obtained ages often differ from those obtained by earlier K-Ar and Rb-Sr studies (e.g., Valizadeh and Cantagrel, 1975;Braud, 1987;Masoudi, 1997;Baharifar, 2004;Baharifar et al, 2004).…”

“…LA-ICP-MS U-Pb zircon ages of the Malayer pluton span an age range between 187 and 162 Ma (mid-Jurassic) (Ahadnejad et al, 2011). According to Ahmadi-Khaladji et al (2007), the Boroujerd granitoid complex has similar U-Pb zircon ages of 172-169 Ma.…”

“…This feature has been detected in the Malayer pluton, where initial 87 Sr/ 86 Sr ratios increase from an average of 0.7085 in the marginal Q-diorites and the 0.7087 in granodiorites, to ca. 0.7011 in the syenogranites from the central part of pluton (Ahadnejad et al 2011). Furthermore, co-existence of antagonistic mineral assemblages (e.g.…”

“…The scattered pattern of elements may have been caused by this process. U-Pb zircon ages (MiddleJurassic) has been obtained from all rock types of complex (Ahadnejad et al 2011) indicate that emplacement of this pluton was performed during the subduction of Neotethys under Central Iran in an active continental margin tectonic setting. In the Pearce et al (1984) discrimination diagrams the studied rocks plot mostly within the field of volcanic arc granites (VAG) (Fig.…”
