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

Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine

Formation

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

Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

All about Diamictite and Pyroxenite Properties

Know all about Diamictite and Pyroxenite properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite belongs to Sedimentary Rocks while Pyroxenite belongs to Igneous Rocks.Texture of Diamictite is Clastic whereas that of Pyroxenite is Clastic, Granular, Phaneritic, Porphyritic. Diamictite appears Banded and Pyroxenite appears Layered, Banded, Veined and Shiny. The luster of Diamictite is grainy, pearly and vitreous while that of Pyroxenite is dull to vitreous to submetallic. Diamictite is available in brown, buff colors whereas Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Pyroxenite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
