Definition
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster

Formation
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
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.

More about Gossan and Anthracite
Here you can know more about Gossan and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gossan and Anthracite consists of mineral content and compound content. The mineral content of Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, Zircon and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all . When we have to compare Gossan vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Gossan is available in brown, brown- black, gold, green, rust colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Gossan is Dull and Banded and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Gossan vs Anthracite. The hardness of Gossan is 4-5 and that of Anthracite is 1-1.5. The types of Gossan are Translocated gossan and Leakage gossan whereas types of Anthracite are Semi-anthracite and Meta-anthracite. 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 Anthracite is black. The specific heat capacity of Gossan is 0.24 kJ/Kg K and that of Anthracite 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 Anthracite is heat resistant, water resistant.
