Formation
Theralite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
  
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.

Theralite vs Anthracite 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. Theralite vs Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Theralite and Properties of Anthracite. Learn more about Theralite vs Anthracite in the next section. The interior uses of Theralite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Anthracite include Not yet used. Due to some exceptional properties of Theralite and Anthracite, they have various applications in construction industry. The uses of Theralite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Theralite and Anthracite
Here you can know more about Theralite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Theralite and Anthracite consists of mineral content and compound content. The mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Igneous Rocks. When we have to compare Theralite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Theralite is available in dark grey to black colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Theralite is Veined and Shiny and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Theralite vs Anthracite. The hardness of Theralite is 7 and that of Anthracite is 1-1.5. The types of Theralite are Teschenite and Essexite 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 Theralite is white while that of Anthracite is black. The specific heat capacity of Theralite is 0.74 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.Theralite is impact resistant, pressure resistant, wear resistant whereas Anthracite is heat resistant, water resistant.
