The Dehaj area, located in the southern part of the Urumieh-Dokhtar magmatic belt, is a well-endowed terrain hosting a number of world-class porphyry copper deposits. These deposits are all hosted in an acidic to intermediate volcano-plutonic sequence greatly affected by various types of the hydrothermal alterations, whether argillic, phyllic or propylitic. Although there are a handful of hithe...

The Lut Block is a potential porphyry-style mineralized region in Iran including the well-explored Shadan porphyry gold-copper deposit, which has an extensive zone of gold- and copper-bearing stockwork-like sheeted veins. structural setting this deposit key to understanding genesis mineralization. Our field studies show that mineralization occurs as steeply dipping ore bodies along NW–SE transp...

introduction a wide variety of world-class porphyry cu deposits occur in the urumieh-dohktar magmatic arc (udma) of iran.the arc is composed of calc-alkaline granitoid rocks, and the ore-hosting porphyry intrusions are dominantly granodiorite to quartz-monzonite (zarasvandi et al., 2015). it is believed that faults played an important role in the emplacement of intrusions and subsequentporphyry...

Bijvard prospect area is located in the northern part of Central Iran zone, Sabzevar zone, about 40 km north of Bardaskan. The rock units exposed in the area include Cretaceous volcano-sedimentary rocks (andesite, basalt, graywacke and conglomerate) that syenogranite porphyry unit has intruded into them.  Mineralization has structural control, with N35E trending, and has altered the andesitic r...
