1 Definition
1.1 Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
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
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
