More About Anthracite

Anthracite is a type of Metamorphic Rocks. The color of rock is one of its important property. Anthracite rock is available in black, brown, dark brown, grey, light to dark grey colors. It is Veined or Pebbled in appearance. The Anthracite mineral content includes Calcite, Clay, Clay Minerals. Its compound content includes Carbon, Hydrogen, Nitrogen, Oxygen, Sulphur. Letโ€™s move on to the types of Anthracite. The types of Anthracite include Semi-anthracite and Meta-anthracite. Fossils are the remains of prehistoric plants or animals which are embedded in rock and preserved in petrified form. Fossils are found only in sedimentary rocks. As Anthracite belongs to Metamorphic Rocks, fossils are not found in it.
