The Byarjomand Batholith with Pre-cambrian age in the north Semnan, north-central Iran, consists of granite, granodiorite, quartz monzodiorite and gabbrodiorite. These rocks have granular texture and occasionally granophyric, pertite and poicelitic textures. Crystal size distribution (CSD) studies can reveal magmatic processes. In order to determine volometric proportion, growth time and nuclea...

The Maksan granitoid is located in the south margin of Lut block, and southeastern Iran. It composed of granite, granodiorite, monzodiorite, quartz monzodiorite, diorite and gabbro. Compostions of biotite from different rock types of Maksan granitoid, i. e., granite, granodiorite, monzodiorite (Quartz monzodiorite), diorite and gabbro in SE of Iran have been documented by electron microprobe. B...

The Bazman intrusive rocks are located in northwest of Iranshahr, south of Lut block, and above of Makran subduction zone. The Bazman intrusive rocks are composed of gabbro, diorite, monzodiorite, qurtze monzodiorite, granodiorite and granite. The Composition of clinopyroxenes is in the diopside-augite range and orthopyroxenes are enstatite. The studied amphiboles are classified as calcic (magn...

Halakabad is located about 30 km south of Sabzevar. Basalt, andesite, hornblende andesite and hornblende dacite are the oldest volcanic rocks cropping out in the study area. Monzodiorite, quartz diorite, quartz monzodiorite, quartz monzonite, and hornblende quartz monzodiorite intruded the volcanic rocks. Application of component analysis is one of the methods that can help to reveal simpler pa...
