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
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

All about Diamictite and Anorthosite Properties
Know all about Diamictite and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite belongs to Sedimentary Rocks while Anorthosite belongs to Igneous Rocks.Texture of Diamictite is Clastic whereas that of Anorthosite is Foliated, Glassy. Diamictite appears Banded and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Diamictite is grainy, pearly and vitreous while that of Anorthosite is pearly to subvitreous. Diamictite is available in brown, buff colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Anorthosite are creating artwork, curling.
