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.

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

Lignite vs Siltstone 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 Siltstone Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt. 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 Siltstone information and Lignite vs Siltstone characteristics in the upcoming sections.

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

More about Lignite and Siltstone

Here you can know more about Lignite and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Siltstone consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Siltstone, 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, Siltstone is available in brown, red, reddish brown colors. Appearance of Lignite is Veined or Pebbled and that of Siltstone is Rough. Properties of rock is another aspect for Lignite vs Siltstone. The hardness of Lignite is 1 and that of Siltstone is 6-7. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Siltstone 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 Siltstone is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Siltstone 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 Siltstone is heat resistant, impact resistant, pressure resistant, water resistant.
