Diamictite (pronounced /ˈdaɪ.əmɪktaɪt/, from Greek δια (dia-): through and µεικτός (meiktós): mixed) is a poorly or non-sorted conglomerate or breccia 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.
