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.

Anthracite vs Travertine 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. Anthracite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anthracite and Properties of Travertine. Learn more about Anthracite vs Travertine in the next section. The interior uses of Anthracite include whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Anthracite and Travertine, they have various applications in construction industry. The uses of Anthracite in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Travertine include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar.
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.
