Archaeological Significance
Formation
Hornblendite 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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Hornblendite and Enderbite
Here you can know more about Hornblendite and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Enderbite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Enderbite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Enderbite, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Hornblendite is Foliated and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Hornblendite vs Enderbite. Hardness of Hornblendite and Enderbite is 6-7. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Enderbite are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornblendite is white to grey while that of Enderbite is white. The specific heat capacity of Hornblendite is 0.84 kJ/Kg K and that of Enderbite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Enderbite is heat resistant, wear resistant.
