Diamictite (/ ˈ d aɪ. əm ɪ k t aɪ t /; from Ancient Greek dia-: 'through' and meiktós (µεικτός): 'mixed') is a type of lithified sedimentary rock that consists of nonsorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone.

Diamictite is a type of rock deposit that is commonly used to identify past glacial events. It can be formed through various processes such as subglacial deposition, debris flows, and volcanic mudflows, and may exhibit features like shear structures and clast pavements.

Diamictite is a poorly sorted or non-sorted terrigenous non-calcareous sedimentary rock that contains variously sized clasts from clay to boulders in a muddy matrix. Diamicton (or diamict) is a non-lithified diamictite (sediment).

C) Former layers of mud, sand, and gravel have been completely homogenized to form this Permian diamictite. D) A coarse-grained pebbly sandstone where gravel is hydrodynamically concentrated along bedding planes.

The main clast type is called diamictite, which literally means two sizes, referring to the unsorted mix of large and small rock fragments found in glacial deposits . Many glacial tills, glacially derived diamictites, include very finely-pulverized rock flour along with giant erratic boulders.

Nov 13, 2021 · Diamicton is a poorly sorted terrigenous sediment. When lithified to sedimentary rock, it’s called diamictite. Diamictite contains a wide range of particle sizes, from gravel to sand, dispersed in a clayey matrix. The nonlithified equivalent of diamictite is diamicton.
