Definition
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.
  
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.
  
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
