Definition
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

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