  1. Diamictite

    Diamictite is a type of sedimentary rock that consists of a wide range of lithified, nonsorted to poorly sorted, terrigenous sediment, i.e. sand or larger size particles that are suspended in a mud matrix. Although the term diamictite is often used for poorly sorted, lithified glacial deposits, this term is applied to this type of sedimentary rock of any origin. This term was coined in 1960 by Flint and others as a purely descriptive term for poorly sorted sedimentary rocks that contain a wide range of particle sizes and avoids any reference to a particular origin. Some Earth scientists restrict the usage of this term to poorly or non-sorted conglomerate or breccia, which consists of sparse, terrigenous gravel suspended in a either a mud or sand matrix. The unlithified equivalent of a diamictite is known either as a diamicton or diamict. Diamictites are often interpreted mistakenly as having an essentially glacial origin, but the most common origin of diamictites is deposition by submarine mass flows like turbidites and olistostromes in tectonically active areas, and they can be produced in a wide range of other geological formation conditions. Possible origins include:
