Diamictite - Wikipedia
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 - an overview | ScienceDirect Topics
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 - Sandatlas
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).

2024年1月22日 · 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.

2021年11月13日 · 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.

2021年11月29日 · Tillite is, on its face, a genetic classification (albeit inferred from texture)--it comes from material ground up and deposited by glaciers, which is characteristically poorly sorted. A tillite is generally a diamictite, but diamictites can also have other origins.

2020年12月13日 · Diamictite is a non-sorted or poorly sorted, noncalcareous, terrigenous sedimentary rock. Diamictite contains a wide range of particle sizes, from gravel to sand, dispersed in a poorly or unstratified clayey matrix.
Diamictite - DWS
Diamictite is a poorly or non-sorted conglomerate with a wide range of clasts, up to 25% of them gravel sized (greater than 2 mm). Diamictites are composed of coarse, angular to well rounded sedimentary clastic fragments, or other type of fragments (igneous and metamorphic rocks) supported by a typically argillaceous (clay sized) matrix.
