Gossan vs Rapakivi Granite


Definition

Definition
Rapakivi Granite is a hornblende-biotite Granite containing large rounded crystals of orthoclase which are mantled with oligoclase

Formation

Formation
Granite is an igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks  
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
