Formation

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

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Charnockite and Hornblendite Reserves. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Charnockite vs Hornblendite information and Charnockite vs Hornblendite characteristics in the upcoming sections.

More about Charnockite and Hornblendite

Here you can know more about Charnockite and Hornblendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Hornblendite 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 Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Hornblendite, 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, Hornblendite is available in black, brown, green, grey colors. Appearance of Charnockite is Veined or Pebbled and that of Hornblendite is Foliated. Properties of rock is another aspect for Charnockite vs Hornblendite. Hardness of Charnockite and Hornblendite is 6-7. The types of Charnockite are Enderbite whereas types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite is white while that of Hornblendite is white to grey. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Hornblendite is 0.84 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 Hornblendite is heat resistant, pressure resistant, wear resistant.
