Formation

Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

More about Anthracite and Mugearite

Here you can know more about Anthracite and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Mugearite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Anthracite is Veined or Pebbled and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Anthracite vs Mugearite. The hardness of Anthracite is 1-1.5 and that of Mugearite is 6. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anthracite is black while that of Mugearite is white to grey. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Mugearite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anthracite is heat resistant, water resistant whereas Mugearite is heat resistant, pressure resistant, wear resistant.
