1.1 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

Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers

5 Formation

5.1 Formation

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

Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
