Aplite and Carbonatite
Definition
Definition
Aplite is a fine-grained granite composed mainly of feldspar and quartz

Formation
Formation
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.
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.

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