Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
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.
