Juvenile granite in the sanandaj sirjan zone nw iran.
Would granite from at plate collision zone.
Continental collision is a phenomenon of the plate tectonics of earth that occurs at convergent boundaries continental collision is a variation on the fundamental process of subduction whereby the subduction zone is destroyed mountains produced and two continents sutured together.
Oceanic crust tends to subduct under continental crust owing to its relative density.
Magmatic arcs and post collision zones.
Where an area of sea separates two plates sediments settle on the sea floor in depressions called geosynclines.
The granites and granite gneisses from a tectono metamorphic complex exposed along the shyok valley in the karakoram region india forms the southern margin of asian plate in the india asia collision zone.
The two mica granite contains xenocrystic material from both the lma and the indian continental crust and indicates s type granite magmatism related to india eurasia continental collision at 35.
Continental collision is a phenomenon of the plate tectonics of earth that occurs at convergent boundaries.
Continental collision is a variation on the fundamental process of subduction whereby the subduction zone is destroyed mountains produced and two continents sutured together.
Continental collision is only known to occur on earth.
In this section we compare the main features of granitic magmatism in both major granite forming systems on earth.
Well really the mechanism that creates granitic magma is subduction of oceanic plates which occurs at convergent boundaries.
In simple terms the opposition between arc and post collisional zones also overlaps with the age old debate on the origin of granitic rocks by i partial melting of older crust or ii.
These rocks have been subjected to mineralogical geochemical and u pb zircon geochronological investigations to constrain the petrogenetic and geodynamic evolution of the karakoram terrane.
