Formation

Wehrlite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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.

More about Wehrlite and Coal

Here you can know more about Wehrlite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Coal consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene 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 Wehrlite vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Wehrlite is Rough and Banded and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Wehrlite vs Coal. The hardness of Wehrlite is 5.5-6 and that of Coal is 1-1.5. The types of Wehrlite are Ultramafic rock 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 Wehrlite is white while that of Coal is black. The specific heat capacity of Wehrlite is 0.63 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.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Coal is heat resistant.
