U-Pb zircon dating, Sr-Nd isotope and petrogenesis of Sarduiyeh granitoid in SE of the UDMA, Iran: implication for the source origin and magmatic evolution

Petrogenesis of Miocene igneous rocks in the Tafresh area (central Urumieh‐Dokhtar magmatic arc, Iran): Insights into mantle sources and geodynamic processes

“…Data from the Tafresh district share similar Nd isotope ratios indicating mantle‐dominant melt, and dominantly high Al contents (i.e., Al 2 O 3 ˃ ca. 17.5) and SiO 2 content less than 58 wt% (Group I, 45–18 Ma) with the Eocene–Early Miocene UDMA mafic suites including these districts: Eshtehard (Babazadeh, D'Antonio, Cottle, et al, 2021), Kahrizak (Yazdani et al, 2019), Ardestan (Babazadeh et al, 2017; Babazadeh, Ghorbani, et al, 2019; Yeganehfar, Ghorbani, Shinjo, & Ghaderi, 2013), Rabor (Chekani Moghadam, Tahmasbi, Ahmadi‐Khalaji, & Santos, 2018), Natanz (Haschke, Ahmadian, Murata, & McDonald, 2010), Haji Abad (Kazemi, Kananian, Xiao, & Sarjoughian, 2019), Saveh (Nouri et al, 2018), Nodoushan (Shahsavari Alavijeh, Rashidnejad‐Omran, Toksoy‐Köksal, Xu, & Ghalamghash, 2019), Sarduiyeh (Nazarinia et al, 2020), Takht (SE UDMA; Pang, Fazlnia, Ji, Jamei, & Jafari, 2020), Raviz‐Shanabad (Salehi Nejad, Ahmadipour, Moinzadeh, Moradian, & Santos, 2021), Deh‐Siahan, Bande‐Bagh, and Baghe‐Khoshk Sharghi (Dargahi, Arvin, Pan, & Babaei, 2010), Kal‐e‐Kafi (Ahmadian et al, 2009), Khalkhab‐Neshveh (Rezaei‐Kahkhaei, Galindo, Pankhurst, & Esmaeily, 2011), Kajan (Golkaram et al, 2016), and Kahak (Moradi, Ghorbani, Jiang, & Christiansen, 2021). Mid‐Miocene Group II districts (<~16 Ma) with SiO 2 content more than 60 wt%, including Niyasar (Honarmand et al, 2014) and Takht (NW UDMA; Haghighi Bardineh, Zarei Sahamieh, Zamanian, & Ahmadi Khalaji, 2018), dominantly manifest lower Al 2 O 3 (≤16 wt%) and Nd isotopes with continental crust signature.…”

Juvenile crust and mantle sources for the Nasrand intrusive rocks, the central Urumieh–Dokhtar magmatic arc, Iran: Insights from elemental and isotopic geochemistry

“…The minor components are hornblende, biotite, apatite, titanite, zircon, and opaque minerals (Figure 3b,c). Granophyric intergrowths of quartz and alkali feldspar are found in some samples and locally contain perthitic K-feldspar as well (Figure 3b 16) Sarduiyeh granitoids from Nazarinia et al (2018) in medium to large sizes with zoning. Alkali feldspar is commonly anhedral, medium to large in size, and in some cases, accompanied by albite blades, and shows perthitic texture (Figure 3b).…”
