Formation
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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 Conglomerate and Aplite Properties
Know all about Conglomerate and Aplite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Aplite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Aplite is Granular, Graphic. Conglomerate appears Shiny and Rounded and Aplite appears Veined or Pebbled. The luster of Conglomerate is dull while that of Aplite is dull to pearly to subvitreous. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Aplite is available in black, grey, orange, pink, white colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones.
