5 Formation

5.1 Formation

Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Felsite 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.

Anthracite vs Felsite 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 Anthracite and Felsite Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. 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. 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 Anthracite vs Felsite information and Anthracite vs Felsite characteristics in the upcoming sections.

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

More about Anthracite and Felsite

Here you can know more about Anthracite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Felsite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Anthracite is Veined or Pebbled and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Anthracite vs Felsite. The hardness of Anthracite is 1-1.5 and that of Felsite is 5-5.5. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Felsite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anthracite is black while that of Felsite is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Felsite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anthracite is heat resistant, water resistant whereas Felsite is heat resistant, impact resistant.
