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.

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Lignite vs Diabase 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 Diabase Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. 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 Diabase information and Lignite vs Diabase characteristics in the upcoming sections.

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

More about Lignite and Diabase

Here you can know more about Lignite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Diabase consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Diabase, 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, Diabase is available in dark grey to black colors. Appearance of Lignite is Veined or Pebbled and that of Diabase is Vesicular. Properties of rock is another aspect for Lignite vs Diabase. The hardness of Lignite is 1 and that of Diabase is 7. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Diabase are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lignite and Diabase is black. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Diabase 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 Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
