Zircon U–Pb ages, geochemical and Sr–Nd–Pb–Hf isotopic constraints on petrogenesis of the Tarom-Olya pluton, Alborz magmatic belt, NW Iran

Geochemistry of skarn and porphyry deposits in relation to epithermal mineralization in the Arasbaran metallogenic zone, NE Tabriz, Iran

“…Re gional ge ol ogy. The mag matic rocks of the AMZ are high-K calc-al ka line to al ka line (Aghazadeh et al, 2011;Asiabanha and Foden, 2012;Cas tro et al, 2013;Nabatian et al, 2016), and are tec toni cally linked to subduction of the Neo-Tethys oce anic crust be neath the Ira nian plate, and subse quent col li sion of Ara bia with Eur asia dur ing the Al pine-Hi - ma la yan orog eny that caused the for ma tion of dif fer ent orogenic belts, in clud ing the AAMB, in which oc cur such de posits as the Mazraeh-e-Shadi, Sungun, Safikhanlo, Sarilar, and oth ers (Alavi, 1994).

Geochemical constraints on the origin and tectonic setting of Chargar intrusions in the Alborz orogenic belt, NW Iran

“…The Tarom intrusions range in composition from quartz monzo-gabbro to diorite, quartz monzodiorite, monzonite, quartz monzonite, monzogranite, granodiorite, alkali granite, granite and syeno-granite (e.g., Nabatian et al 2014Nabatian et al , 2016Esmaeli et al 2015;Mehrabi et al 2016;Kouhestani et al 2017Kouhestani et al , 2018Yasami et al 2018). These I-type intrusions have high-K calc-alkaline to shoshonitic affinity and metaluminous characteristics (Irannezhadi et al 2007;Azizi et al 2009;Nabatian et al 2014Nabatian et al , 2016Yasami et al 2018) and show enrichment in Large Ion Lithophile Elements (LILE) and Light Rare Earth Elements (LREE) and negative anomalies in High Field Strength Elements (HFSE) and depletion in Heavy Rare Earth Elements (HREE) (Nabatian et al 2014(Nabatian et al , 2016Yasami et al 2018). The Tarom plutons show subduction-related arc magmatic signatures (Nabatian et al 2016).…”

“…Tarom plutons parental magma derivation from the sub-continental lithospheric mantle source was suggested by geochemical and isotopic data, which were fluids and melts metasomatized from the subducted Neotethyan slab with a minor crustal contribution. Decompression melting in the final stage of Neotethyan subduction through slab rollback or shortly after the cessation of arc magmatism was created by subsequent hot asthenospheric upwelling and lithospheric extension (Nabatian et al 2016).…”

The Shah-Ali-Beiglou Zn-Pb-Cu (-Ag) Deposit, Iran: An Example of Intermediate Sulfidation Epithermal Type Mineralization

“…The northwestern part of the AAMB includes two mineralized subzones named the Ahar-Arasbaran Belt (AAB) in the north and the Tarom-Hashjin metallogenic province (THMP) in the south (Figure 1) [2,3]. The THMP is known as an economically important metallogenic province in Iran [2,14,15] and includes a variety of mineral deposits such as Mn deposits, iron-skarns, manto-type Cu-Ag deposits, and Zn-Pb-Cu±Au-Ag epithermal deposits [3,[16][17][18][19]. All of these deposits are variably attributed to post-collisional magmatic processes (e.g., [20][21][22]).…”
