5 Formation

5.1 Formation

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.

Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.

Felsite vs Oil shale 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 Oil shale 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. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. 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 Oil shale information and Felsite vs Oil shale characteristics in the upcoming sections.

Due to some exceptional properties of Felsite and Oil shale, 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 Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.

More about Felsite and Oil shale

Here you can know more about Felsite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Oil shale consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Oil shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Oil shale is Muddy. Properties of rock is another aspect for Felsite vs Oil shale. The hardness of Felsite is 5-5.5 and that of Oil shale is 2-3. The types of Felsite are Not Available whereas types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Felsite and Oil shale is white. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Oil shale is 0.39 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 Oil shale is heat resistant, impact resistant.
