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

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

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