Definition
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

Formation
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
