Definition

Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

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.

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
