Gossan vs Coal

Gossan 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 Gossan and Coal Reserves. Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.. 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 Gossan vs Coal information and Gossan vs Coal characteristics in the upcoming sections.

Gossan 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. Gossan vs Coal characteristics assist us to distinguish and recognize rocks.

Gossan is available in brown, brown- black, gold, green, rust colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Gossan is Dull and Banded and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Gossan vs Coal. The hardness of Gossan is 4-5 and that of Coal is 1-1.5. The types of Gossan are Translocated gossan and Leakage gossan 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 Gossan is white to grey while that of Coal is black. The specific heat capacity of Gossan is 0.24 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.Gossan is heat resistant, impact resistant, pressure resistant whereas Coal is heat resistant.
