1.1 Definition
Alkali feldspar granite, also known as red granite, is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

5.1 Formation
Alkali fledspar granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.
