The Bazman granitoid is located in the south margin of Lut block, and southeastern of Iran. It composed of granite, granodiorite, monzodiorite, quartz monzodiorite, diorite and gabbro. Plagioclase, feldspar, quartz, hornblende and biotite are the major minerals; sphen, apatite, zircon, magnetite and ilmenite are the main accessory minerals. Amphibole mineral chemistry is calcic in composition a...

Incheh granitoid intrusion is located east of Herris, East-Azerbaijan Province. It intruded into the older rock units including Eocene volcanic – volcaniclastics. Compositionally, this intrusion ranges from diorite-quartz diorite to monzonite. Chemical composition of its major minerals such as feldspars, amphibole and clinopyroxene analyzed using electron probe micro-analyzer (EPMA) for thermob...

Khezr-Abad pluton is cropped out in North-West of Taft. This granitoid seems to be younger than the surrounding metamorphosed rocks, particularly the lower cretaceous limestones and probably is implaced during Oligo-Miocene. The most volumetric abundances of the igneous rocks are: granodiorite, granite, quartzmonzo-diorite, quartz-diorite, and in a lesser amount tonalite, quartz-syenite and ...

The Zahri granitoid body has intruded into the Late Cretaceous ophiolitic rocks syn-tectonically. This granitoid with NW–SE general trend was emplaced along the terminations of Nehbandan shear system in the northern Sistan suture zone during the Early Eocene. Development of magmatic to low temperature solid-state fabrics have shown the progressive deformation with decreasing melt content during...

Abstract Cretaceous igneous rocks in SW Borneo are significant for investigating the Paleo-Pacific subduction and regional correlation. This paper presents new zircon ages Sr–Nd–Pb–Hf–O isotopic whole-rock geochemical data granitoids Schwaner Mountains. These granitoid samples yield formation of 92–80 Ma can be geochemically subdivided into Group 1 biotite granite granodiorite 2 monzogranite. h...

the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...

The Miocene Qohrud granitoid intrusion consists of granite, granodiorite and tonalite and is located in the Urmia-Dokhtar magmatic belt. Intrusion of magmatic rocks into the various sedimentary rocks including shale, sandstone, limestone and marl, with Jurassic to Eocene age, has caused contact metamorphism of the surrounded rocks. Varity of hornfelses and skarns are formed in this regards. Hyd...

The granitoid intrusions of Dehnow, which is located  in northwest of Mashhad in immediate contact with garnet-rich hornfels, contain large crystals of garnets. They provide an excellent opportunity to study the effect of host rocks in contamination of a garnet-bearing granitoid magma. The garnet crystals contain abundant inclusions that are indicative of igneous phases and are arranged in a ci...
