bibi maryam granitoid body with about 5 km2 has intruded into ophiolite mélange complex in sistan suture zone, in east of iran. thermal effects of this body on the host rocks show that this activity occurred after emplacement of ophiolite mélange. this intrusive body with general northwest – southeast trend is mainly tonalite-quartz diorite but there is a minor unit as dykes of granodiorite in ...

This study evaluates the geological attributes of rocks within Abu Ghalaga area using spatial, geochemical, and petrographic approaches. ASTER Landsat imagery processed band ratio principal component analysis were used to map hydrothermal alterations, while a regional tectonic evaluation was based on automated extraction lineaments from digital elevation model. Geochemical analyses then employe...

Abstract Granite rocks are currently one of the foremost raw materials that can be used for various economic purposes such as ornamentation and building materials, because they do not possess radioactive concentrations have good physical mechanical properties. The granite north Um Taghir connected to neoproterozoic integrated Arabian-Nubian Shield (ANS), which lies in Northeast Africa. Inductiv...

The Karakoram Terrane (KT) represents the southern margin of Eurasian Plate, mainly consisting Late Jurassic-Early Cretaceous subduction-related granites and post-collisional Miocene leucogranites, which intrude Neo-Proterozoic basement. We report for first time existence Cryogenian KT basement as recorded from geochemistry geochronology tonalite gneiss (ca. 806 Ma) in southeastern terrane, NW ...

The Shaitian granite complex (SGC) spans more than 80 Ma of crustal growth in the Arabian–Nubian Shield southeast Egypt. It is a voluminous composite intrusion (60 km2) comprising host tonalite massif intruded by subordinate dyke-like masses trondhjemite, granodiorite and monzogranite. tonalite, turn, encloses several, fine-grained amphibolite enclaves. U-Pb zircon dating indicates wide range c...

The Saglek-Hebron Complex (SHC) located in Northern Labrador, Canada, includes some of the oldest crustal rocks on Earth. This granite-greenstone terrain is dominated by trondhjemite, Mg-rich tonalite, granite, with subordinate granodiorite, and recorded over one billion years early magmatic history between ∼3900 Ma ∼2700 Ma. New in-situ U-Pb analyses zircons from eighteen rock samples, suggest...
