Archaeological Significance
Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.
