The Kuh-e Mish plutonic complex (KPC) is located about 30 km south of Sabzevar. Based on tectonic division, it is part of Sabzevar zone. The Stratigraphic units of the area are conglomerate, tuff, and sandstone of the Paleogene, radiolarites, andesite and tuff unit of Upper Cretaceous. This collection consists of two plutonic rocks types. (1): The granitoid complex of northern Kuh-e Mish which ...

The East Kunlun Orogenic Belt is considered as one of the important gold mineralization regions in Tethys tectonic domain. These orogenic deposits are related to intermediate-acid intrusions formed at end Paleo-Tethys evolution, but petrogenesis controversial. This paper presents a new study on geochemistry zircon U-Pb, O, S, and Pb isotopic compositions Asiha quartz diorite, granite porphyry, ...

Kuh e-Dom intrusion, located at the northeast of Ardestan, consists of granodiorite and diorite. The granodiorites have been intruded by various basic dikes. Plutonic rocks are mainly composed of plagioclase, biotite, amphibole, pyroxene, alkali-feldspar and quartz. Based on microprobe analysis, the biotite is classified as magnesiobiotites which typically occur at calc-alkaline orogenic igneou...

The Homond Cu-Au porphyry prospecting area is located southwest of Birjand. Subvolcanic monzonitic to dioritic rocks are highly altered. The main alteration zones are: quartz-sericite-calcite-pyrite, propylitic and carbonate. The content of major, trace and rare earth elements (REE) of the rocks changes due to alteration. The changes are less in some such as TiO2, MnO, P2O5, Nb, Gd, Y, Eu and h...
