Petrogenesis and geodynamics of the Early Miocene Kashan granitoids in the central Urumieh-Dokhtar Magmatic Arc, Iran [PDF]
Scientific ReportsThis study investigates the early Miocene granitoids (rhyolites, dacites, granodiorites, and diorites) from the Kashan area in the central Urumieh-Dokhtar Magmatic Arc of Iran, to constrain their sources and geodynamic processes. Zircon U–Pb ages, zircon

Evolution of the volcanic mechanism in the central part of the Urumieh-Dokhtar magmatic arc
Journal of Economic Geology, 2021 Introduction Cenozoic volcanic activities in the Urumieh-Dokhtar Magmatic Arc (UDMA) have occurred in three main pulses of Eocene, upper Oligocene-Pliocene, and Pio-Quaternary (Dilek et al., 2010, Sayari, 2015).

Lithos, 2021 Abstract We present regional variations of whole-rock Sr/Y and (La/Yb)N ratios of magmatic rocks along the Cenozoic Urumieh-Dokhtar and Alborz magmatic belts, Iran. Both the magmatic belts are located at the north of the main Zagros Neo-Tethyan suture.

Journal of Economic Geology, 2021 Introduction Granitoids are one of the most abundant and common igneous rocks in the continental crust and they formed the world's largest batholiths. They are widely distributed in Precambrian to Cenozoic orogenic belts (e.g., Raymond, 2002), but some ...

Geosciences (Switzerland), 2023 Magnetic fabric, paleomagnetic, and petrophysical studies were conducted on rocks in the Tafresh area of the central Urumieh-Dokhtar magmatic arc in Iran. The samples included Late Triassic dark gray sandstone, a mafic dyke, diorites, and a felsic dyke in the Zaghar region.

Lithos, 2020 Abstract Geochemical data on igneous rocks of the Urumieh-Dokhtar magmatic arc (UDMA) are used to reconstruct temporal variations in crustal thickness during the Tertiary. We use two approaches, (1) whole rock Sr/Y and La/Yb ratios, and (2) Nd isotopes and an assimilation model for magma genesis.

Magnetite chemistry in the Dalli porphyry Cu-Au deposit, central Urumieh-Dokhtar Magmatic Arc (UDMA)
Journal of Economic Geology, 2023 The Dalli porphyry Cu-Au deposit is located in the central parts of Urumieh –Dokhtar Magmatic Arc (UDMA). This deposit is formed via the emplacing of Miocene intrusions mainly containing diorite and quartz diorite within the Eocene andesite and ...

Ore Geology Reviews, 2021 Abstract The Cenozoic Urumieh-Dokhtar magmatic arc (UDMA) is considered as one of the major Cu-bearing regions of the world, with high potential for the occurrence of porphyry Cu ± Mo ± Au systems. This study conducts a comprehensive synthesis of geological, geochronological, and geochemical data of intrusive igneous rocks in selected productive,
