1.1 Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

5 Formation
5.1 Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
