slate
Granite does not turn into limestone. Granite is an igneous rock originating from volcanic activity. Limestone is a sedimentary rock laid down in the oceans millions of years ago. Limestone does turn into marble when subjected to huge pressures and heat. It is found areas with a lot of seismic activity like Itlay and Turkey.
shale → slate → phyllite → schist → gneiss
When rocks are subjected to high pressures, they can change their formation and appearance. This process, which alters the structure of a rock, is called metamorphism.
Granite becomes Sandstone when water erodes the Granite on Earths surface, and then deposits the sediment.
It would become metamorphic rock.
gneiss
Granite becomes metamorphic by being subjected to immense heat and pressure, turning into gneiss.
If enough heat and pressure is applied (40000 to 60000 times atmospheric pressure and 900 to 1300 degrees Celsius), granite or any other allotrope of carbon can be turned into diamond.
slate
Heat and pressure
When emplaced granite is subjected to pressures and temperatures from mountain building processes due to tectonic plate movements, the component minerals are essentially realigned perpendicularly to the direction of the stress.

Heat and pressure
Through heat and pressure
Heat and pressure cause granite to change to gneiss.
Graphite has its own atomic structure of its basic carbon atoms. Subjecting it to very high temperature and pressure would not change its structure. Carbon, when subjected to very high temperature and pressure can be crystallized into diamond structures.
