5 Formation

5.1 Formation

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Foidolites 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.

Lignite vs Foidolite 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 Lignite and Foidolite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%. 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 Lignite vs Foidolite information and Lignite vs Foidolite characteristics in the upcoming sections.

Lignite vs Foidolite 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. Lignite vs Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Foidolite. Learn more about Lignite vs Foidolite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Lignite and Foidolite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Foidolite include As dimension stone, Cement manufacture, For road aggregate.

More about Lignite and Foidolite

Here you can know more about Lignite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Foidolite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Foidolite, the texture, color and appearance plays an important role in determining the type of rock. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Foidolite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Lignite is Veined or Pebbled and that of Foidolite is Dull. Properties of rock is another aspect for Lignite vs Foidolite. The hardness of Lignite is 1 and that of Foidolite is 1.5. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Foidolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lignite is black while that of Foidolite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Foidolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Lignite is heat resistant whereas Foidolite is heat resistant, wear resistant.
