Formation
Formation
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive 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 Latite and Aplite Properties
Know all about Latite and Aplite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Aplite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Aplite is Granular, Graphic. Latite appears Rough and Aplite appears Veined or Pebbled. The luster of Latite is subvitreous to dull while that of Aplite is dull to pearly to subvitreous. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Aplite is available in black, grey, orange, pink, white colors. The commercial uses of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo) and that of Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones.
