Formation

Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.   
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.

Syenite 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 Syenite and Lignite Reserves. Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals. 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 Syenite vs Lignite information and Syenite vs Lignite characteristics in the upcoming sections.

Syenite 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. Syenite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Syenite and Properties of Lignite. Learn more about Syenite vs Lignite in the next section. The interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Syenite and Lignite, they have various applications in construction industry. The uses of Syenite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Lignite include For road aggregate, Steel production.

More about Syenite and Lignite

Here you can know more about Syenite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Syenite and Lignite consists of mineral content and compound content. The mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Syenite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Syenite is Banded and Foilated and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Syenite vs Lignite. The hardness of Syenite is 5.5-6 and that of Lignite is 1. The types of Syenite are Shonkinite 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 Syenite is white while that of Lignite is black. The specific heat capacity of Syenite is 0.92 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.Syenite is heat resistant, impact resistant, wear resistant whereas Lignite is heat resistant.
