Felsite vs Coal

Felsite vs Coal 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 Felsite and Coal Reserves. Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Felsite vs Coal information and Felsite vs Coal characteristics in the upcoming sections.

Felsite vs Coal 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. Felsite vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Felsite and Properties of Coal. Learn more about Felsite vs Coal in the next section. The interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Felsite and Coal, they have various applications in construction industry. The uses of Felsite in construction industry include Arrowheads, Cutting tool, Knives, Scrapers, Spear points and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.

More about Felsite and Coal

Here you can know more about Felsite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Coal consists of mineral content and compound content.

Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Felsite vs Coal. The hardness of Felsite is 5-5.5 and that of Coal is 1-1.5. The types of Felsite are Not Available whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Felsite is white while that of Coal is black. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Coal is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Felsite is heat resistant, impact resistant whereas Coal is heat resistant.
