Gossan vs Blue Granite


Definition

Definition
Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar

Formation

Formation
Blue Granite is an igneous rock which is a variety of Larvikite and is known mainly for the presence of thumbnail-sized crystals of feldspar.   
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
