Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
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

Archaeological Significance
Formation
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Carbonatite and Diamictite Properties
Know all about Carbonatite and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Diamictite belongs to Sedimentary Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Diamictite is Clastic. Carbonatite appears Dull, Banded and Foilated and Diamictite appears Banded. The luster of Carbonatite is subvitreous to dull while that of Diamictite is grainy, pearly and vitreous. Carbonatite is available in black, brown, green, grey, pink, white colors whereas Diamictite is available in brown, buff colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Diamictite are commemorative tablets, creating artwork, production of lime.
