Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Aplite is a fine-grained granite composed mainly of feldspar and quartz

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.
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

All about Carbonatite and Aplite Properties
Know all about Carbonatite and Aplite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Aplite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Aplite is Granular, Graphic. Carbonatite appears Dull, Banded and Foilated and Aplite appears Veined or Pebbled. The luster of Carbonatite is subvitreous to dull while that of Aplite is dull to pearly to subvitreous. Carbonatite is available in black, brown, green, grey, pink, white colors whereas Aplite is available in black, grey, orange, pink, white colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones.
