Definition

Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities

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

Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
