Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

More about Charnockite and Diatomite
Here you can know more about Charnockite and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Diatomite consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Diatomite, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Diatomite is available in grey, white, yellow colors. Appearance of Charnockite is Veined or Pebbled and that of Diatomite is Soft. Properties of rock is another aspect for Charnockite vs Diatomite. The hardness of Charnockite is 6-7 and that of Diatomite is 1. The types of Charnockite are Enderbite whereas types of Diatomite are Diatomite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Diatomite is white. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Diatomite is 0.90 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Charnockite is heat resistant, wear resistant whereas Diatomite is heat resistant.
