Archaeological Significance
Formation
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
