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.

Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

More about Anthracite and Travertine

Here you can know more about Anthracite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Travertine consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Travertine, 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, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Anthracite is Veined or Pebbled and that of Travertine is Fibrous. Properties of rock is another aspect for Anthracite vs Travertine. The hardness of Anthracite is 1-1.5 and that of Travertine is 3-4. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Travertine are Thermal Travertine and Tufa. 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 Travertine is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Travertine is 1.09 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 Travertine is impact resistant, pressure resistant, wear resistant.
