5.1 Formation

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

Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

Syenite vs Coal 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 Coal Reserves. Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Coal information and Syenite vs Coal characteristics in the upcoming sections.

Syenite vs Coal 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 Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Syenite and Properties of Coal. Learn more about Syenite vs Coal in the next section. The interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Syenite and Coal, 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 Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.

More about Syenite and Coal

Here you can know more about Syenite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Syenite and Coal 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 Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Syenite vs Coal, 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, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Syenite is Banded and Foilated and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Syenite vs Coal. The hardness of Syenite is 5.5-6 and that of Coal is 1-1.5. The types of Syenite are Shonkinite whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. 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 Coal is black. The specific heat capacity of Syenite is 0.92 kJ/Kg K and that of Coal is 1.32 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 Coal is heat resistant.
