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.

Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
