PETROGENESIS AND ORIGIN OF THE CHENAR GRANITOID STOCK, NW OF KERMAN, IRAN: EVIDENCE OF NEOTETHYS SUBDUCTION RELATED ARC MAGMATISM
The lower to middle Miocene Chenar granitoid stock, a part of Central Iranian volcanic belt, is intruded into Eocene volcano-sedimentary complex in northwestern Kerman in south Central Iran. The Chenar granitoid stock consists mainly of coarse to medium grain granodiorite and monzogranite with subordinate tonalite and syenogranite. Alkali granites as aplitic veins and quartz dioritic dykes freq...

The Alvand plutonic complex is composed of various plutonic rocks, mafic and felsic dikes (pegmatites and aplites). Pegmatites and aplites consist of quartz, feldspar, mica, tourmaline, garnet and allanite. Based on the mineralogycal compound, pegmatites can be divided into tourmaline-garnet-muscovite-bearing, aluminosilicate-bearing and tourmaline-bearing pegmatites and aplites are composed of...
متن کاملPostcollisional mafic igneous rocks record crust-mantle interaction during continental deep subduction
Findings of coesite and microdiamond in metamorphic rocks of supracrustal protolith led to the recognition of continental subduction to mantle depths. The crust-mantle interaction is expected to take place during subduction of the continental crust beneath the subcontinental lithospheric mantle wedge. This is recorded by postcollisional mafic igneous rocks in the Dabie-Sulu orogenic belt and it...

متن کاملOceanic mafic magmatism in the Siletz terrane, NW North America: Fragments of an Eocene oceanic plateau?
Article history: Received 11 October 2016 Accepted 5 January 2017 Available online 14 January 2017 The Siletz terrane, a predominantly mafic accreted oceanic terrane, is located in the Cascadia forearc region of Oregon, Washington and Vancouver Island. The terrane represents a late Palaeocene–Eocene large igneous province that consists of pillow lavas, massive flows and intrusive sheets. Previo...
