Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

All about Enderbite and Chert Properties
Know all about Enderbite and Chert properties here. All properties of rocks are important as they define the type of rock and its application. Enderbite belongs to Igneous Rocks while Chert belongs to Sedimentary Rocks.Texture of Enderbite is Granular whereas that of Chert is Banded, Rough. Enderbite appears Veined or Pebbled and Chert appears Glassy or Pearly. The luster of Enderbite is while that of Chert is waxy and dull. Enderbite is available in black, grey, orange, pink, white colors whereas Chert is available in black, brown, green, grey, red, white colors. The commercial uses of Enderbite are curling, gemstone, laboratory bench tops, tombstones and that of Chert are creating artwork, gemstone, in fire-starting tools, jewelry, to ignite fire, used in flintlock firearms.
