1.1 Definition
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

5.1 Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.
