Definition
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
