5.1 Formation
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.
Novaculite forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The formation of Novaculite can be either of chemical or biological origin.

Coal vs Novaculite 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 Coal and Novaculite Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture. 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 Coal vs Novaculite information and Coal vs Novaculite characteristics in the upcoming sections.

Coal vs Novaculite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Coal vs Novaculite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Novaculite. Learn more about Coal vs Novaculite in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Novaculite include Countertops, Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Coal and Novaculite, they have various applications in construction industry. The uses of Coal in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Novaculite include Arrowheads, Building houses or walls, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Knives, Landscaping, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone, Spear points, Used to sharpen metal tools and weapons.

More about Coal and Novaculite

Here you can know more about Coal and Novaculite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Novaculite consists of mineral content and compound content. The mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon and mineral content of Novaculite includes Quartz, Silicon. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Novaculite, the texture, color and appearance plays an important role in determining the type of rock. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Novaculite is available in black, brown, green, grey, red, white colors. Appearance of Coal is Veined or Pebbled and that of Novaculite is Glassy or Pearly. Properties of rock is another aspect for Coal vs Novaculite. The hardness of Coal is 1-1.5 and that of Novaculite is 7. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Novaculite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Coal is black while that of Novaculite is colorless. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Novaculite is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Novaculite is heat resistant, impact resistant, pressure resistant, wear resistant.
