The Hezar Igneous Complex (HIC) in the south-eastern part of Urumieh-Dokhtar magmatic arc, is the most prominent magmatic feature in the Kerman Porphyry Copper Belt, that understanding magmatic evolution of which may shed light on the tectonomagmatic development of this less-studied part of an important magmatic arc in the Neotethys realm. The HIC has been developed in the the intersection of t...

At the south of Bardsir, Kerman province, Iran, southeastern part Urmia-Dokhtar magmatic arc (UDMA), a large number gabbroic intrusions are intruded into Eocene lava flows and pyroclastic rocks with form small stocks dykes. In this paper, geochemical variations, evolutions, origin these investigated. The studied characterized by fine-grained margins resulting from rapid cooling flow differentia...

introduction the generation and evolution of granitic magmas has been a hot debated subject among petrologists. the diversity of their origin has led different authors to propose that these rocks are not simple in their origin and might be generated in more ways than one. in the past several decades, many petrologists used a variety characteristics to subdivide the granitoid rocks. such proposa...

late miocene–pliocene calc-alkaline volcanic rocks are exposed southeast of isfahan in the urumieh-dokhtar magmatic belt. volcanic rocks consist of lava flows and domes, chiefly basaltic andesites, andesites and dacites. minerals in the volcanic rocks exhibit degrees of disequilibrium features. plagioclase as dominant mineral in these rocks generally displays reverse and oscillatory zoning; sie...

the darreh-zar porphyry copper deposit, located in the urumieh – dokhtar magmatic belt, lies about 10 km southeast of sar-cheshmeh porphyry copper deposit. the ore body with hydrothermally altered zones including potassic, chlorite-sericite, sericite, argillic and propylitic all related to the darreh-zar porphyry stock intruded the eocene volcanic rocks. pyrite, chalcopyrite, molybdenite, with ...
