Fadiheh copper-gold prospect area in northwest of Torbat-e Heydariyeh in Khorasan Razavi Province is located in the central part of the Khaf-Kashmar-Bardaskan magmatic belt. This area includes outcrops of Eocene volcanic-pyroclastic units with felsicـintermediate nature. The lavas are andesite and latite, and pyroclastic units include rhyodacitic tuff, andesitic lithic tuff and ignimbrite. Intr...
the neogene intrusion masses in the noudeh-enghelab area located to the north of sabzevar ophiolite have cut the late cretaceous ophiolitic rocks, sedimentary- volcanic and eocene volcanic rocks and have been covered by pliocene and quaternary deposits. the margin is of lava with basalt, phyric andesite-basalt and andesite and the central parts (dome shaped) composed of phyric andesite-trachyan...
East misho granitoid intrusion body, a part of Alborz-Azarbaijan zone, is located about 60 Km north west of Tabriz, NW Iran. This pluton with an area of about 50 km2 has cut percamberian unmetamorpic sedimentary rocks and, is covered with Permian sedimentary rocks with igneous nonconformity. Litological composition of the studied pluton displays a range of alkali granite, monzogranite and syeno...
The studied area located in south and south western Arak town and are the part of Sanadaj-Sirjan Zone. The plutonic rocks in Astaneh and Boroujerd areas are quartz diorite, granodiorite and monzogranite. In addition to plutonic rocks, subvolcanic rocks of rhyodacite composition are present in Astaneh area. In general, in these areass mineral assemblage is the same in different units. The common...
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...
Introduction: Shock-metamorphic effects including shatter cones, planar deformation features (PDFs) in quartz grains, and both E-and S-type pseu-dotachylites were discovered in deeply eroded Ar-chean granites near the Yarrabubba homestead in Western Australia (119°50'E, 27°10'S). Preliminary estimates indicate that the Yarrabubba impact structure is of a Paleoproterozoic age and at least 30 km ...
In provenance investigation of Quaternary sediments, quartz luminescence sensitivity (QLS) has been employed as a technique. The weathering and influence on the earliest signs sedimentary require more consideration. this study, QLS properties eight samples Permian biotite monzogranite from borehole in southern tropics China are investigated. degree chemical does not correspond with values that ...
Older and younger granitoids are widespread throughout the basement rocks of NE Egypt. Therefore, they are played a significant role in the evolution of the Pan-African crust. The Wadi El Sheikh-Gabal Saint Katherine area comprise three distinctive magmatic granitoid suites, namely: (1) calc-alkaline older quartz monzodiorite-tonalite suite (COG), (2) calcalkaline younger monzogranite suite (CY...
The study area is located in northeastern Iran (south of Mashhad). Paleo-Tethys Ocean opened during Silurian time and subduction under Turan plate was started in Late Devonian. By Late Triassic (225 Ma) there was no Paleo-Tethys left on an Iranian transect, therefore Turan plate obducted over Iran Plate. Two stages of low grade regional metamorphism are exposed, that are related to Hercynian (L...
In the Jebilet massif (Variscan belt, Morocco), two peraluminous granodioritic plutons (the Eastern and Central plutons) are spatially associated with a regional shear zone. The pluton includes Tabouchent, Bramram Bamega intrusions, which represent variably eroded portions of an arcuate apical part pluton. intrusions composed biotite ± cordierite-bearing granodiorite that is crosscut by tourmal...
