Archaeological Significance
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.
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.

All about Aplite and Latite Properties
Know all about Aplite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Aplite and Latite belong to Igneous Rocks.Texture of Aplite is Granular, Graphic whereas that of Latite is Aphanitic to Porphyritic. Aplite appears Veined or Pebbled and Latite appears Rough. The luster of Aplite is dull to pearly to subvitreous while that of Latite is subvitreous to dull. Aplite is available in black, grey, orange, pink, white colors whereas Latite 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 Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
