5 Formation

5.1 Formation

Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

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.

Basalt vs Lignite 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 Basalt and Lignite Reserves. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Basalt vs Lignite information and Basalt vs Lignite characteristics in the upcoming sections.

Basalt vs Lignite 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. Basalt vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basalt and Properties of Lignite. Learn more about Basalt vs Lignite in the next section. The interior uses of Basalt include Floor tiles, Homes, Hotels and Kitchens whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Basalt and Lignite, they have various applications in construction industry. The uses of Basalt in construction industry include Arrowheads, As dimension stone, Cobblestones, Cutting tool, Rail track ballast, Roadstone and that of Lignite include For road aggregate, Steel production.

More about Basalt and Lignite

Here you can know more about Basalt and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basalt and Lignite consists of mineral content and compound content. The mineral content of Basalt includes Olivine, Plagioclase, Pyroxene and mineral content of Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Basalt vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Basalt is available in black, brown, light to dark grey colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Basalt is Dull and Soft and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Basalt vs Lignite. The hardness of Basalt is 6 and that of Lignite is 1. The types of Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basalt is white to grey while that of Lignite is black. The specific heat capacity of Basalt is 0.84 kJ/Kg K and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basalt is heat resistant, pressure resistant, wear resistant whereas Lignite is heat resistant.
