Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral.
Why are certain granites enriched in vanadium.
Rudnick 1995 that is much of the continental crust cannot have formed through simple mantle melting events therefore some other process or combination of processes must occur to form such evolved.

And 2 metasomatizing fluids that circulated along shear zones.
Rather it most often occurs in oxides as the minerals uraninite uo 2 or pitchblende partially oxidized uraninite conventionally given as u 3 o 8 in solution uranium travels in molecular complexes with carbonate sulfate and chloride as long as the chemical conditions are oxidizing.
As a catalyst for the chemical industry.
World vanadium resources in 2012 were estimated to be 63 million metric tons which include about 14 million metric tons of reserves.
Uranium is also found associated with certain igneous rocks such as granite and porphyry.
