In northwestern Iran, magmatic activity occurred during three main intervals: The Cretaceous, Eocene, and Miocene-Quaternary. The first two phases of magmatic activity are …
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 …

IntroductionAbout 75% of world copper, 50% of molybdenum, and 20% of gold are produced from porphyry copper deposits (Sillitoe, 2010) with an average ore grade of 0.45–1.5% Cu …
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 …

ABSTRACT Late Eocene–Oligocene volcanic rocks in the eastern Saveh region of the Urumieh-Dokhtar magmatic arc (UDMA) are representative of Paleogene magmatic activity …
Igneous rocks in central Iran preserve proof of several episodes of Late Mesozoic–Cenozoic Neotethyan subduction, and record temporal and spatial variations from subduction to …
The late Eocene high-K to shoshonitic Zajkan intrusion, situated in the Tarom-Hashtjin magmatic belt (THMB), NW Iran, ranges in composition from gabbro to pyroxene quartz …
Tozlou Pb-Zn mineralization,~ 250-300m long, and~ 50m thick, is hosted by limestone units of the Qom Formation. The main mineralization zone occurred as vein-veinlets and vug infill …
