Granitoid bodis of Kuhmish are located about 30 km south of Sabzevar city. In terms of tectonic classification, Kuhmish granite was considered to be part of Sabzevar zone. Conglomerate, tuff, sandstones of Paleogene age and tuff units, radiolarites, andesite and diorite with UpperCretaceous age form the main litological units of the study area. Granitoid bodies involves aacidic part with combin...
SUMMARY Penetrative petro-fabrics in plutons, particularly late-stage solid-state fabrics, are usually considered to record regional tectonism. However, these fabrics fundamentally ambiguous correlate with magma-chamber processes or tectonics. Understanding the of fabric formation requires a proper understanding pluton and emplacement mechanism. In this paper, we provide case study transition f...
In recent years, with the exploration and development of granite buried-hill oil gas reservoirs, petrophysics research has played an important role in study reservoir characteristics fluid identification. Through analysis relationship between fluid-bearing petrophysical parameters reservoir, seismic response changes caused by can be determined. Mesozoic granites coastal area Fujian Province eas...
The stability of tunnel site depends upon the deformation behaviors surrounding rocks, including joint density, mineral composition, micro cracks, and grain boundaries. aim this study was to analyze mechanical properties Besham Complex in Northern Pakistan terms petrography analysis. complex is prone as it bounded by Main Mantle Thrust (MMT) north, Thakot fault (Tf) east, Swat block west. In ar...
The closing time of the Paleo-Asian Ocean and tectonic evolution northern margin North China Craton are still controversial. geochronology geochemistry Zhaojinggou monzogranite pluton provide new constraints on late Paleozoic closure in southern Central Asian Orogenic Belt (CAOB). yielded a zircon U-Pb age 286.7 ± 1.2 Ma. Due to characteristics low–moderate Mg# values (25.87–39.21), low Fe2O3T ...
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 study area is a part of the Sanandaj- Sirjan metamorphic belt. The Hamadan metamorphic rocks can be divided into three groups including regional metamorphic rocks, contact metamorphic rocks and migmatites. Garnet crystals are usually common in all of the metamorphic rocks (except for slates and phyllites) and in the igneous rocks (i.e. aplite, pegmatite and monzogranite). These garnets, fro...
The Goushe granitoid Pluton is located southeast of Boroujerd. The study area is composed of granite, granodiorite and the microgranular enclaves located in it with the granodiorite to quartzmonzodiorite combination. The microgranular enclaves presence along with evidence of the presence of the non-equilibrium textures such as dissolved margin and plagioclase zoning, sieve textures, mafic clots...
Garagheh granitoid is located in the northwest Zahedan batholite and is exposed in Zahedan-Saravan granitoid belt and Sistan suture zone. This granitoid is composed of granite (synogranite, monzogranite) and granodiorite. These rocks have mainly consist of plagioclase, orthoclase, microcline, quartz, biotite and hornbelend with granoular texture. This pluton cut by microdioritic dykes. Garagheh...
The Mamzar granitoid pluton is located in the Kerman Province and structurally in southeast of Urumieh-Dokhtar magmatic zone. Based on petrographic studies, the granitoid consist of four rock type of diorite, tonalite, granodiorite and monzogranite. They are mainly composed of plagioclase (andesine), alkali-feldspar (orthoclase), quartz, amphibole (magnesiohornblende), biotite and clinopyroxene...
