Features
Easily splits into thin plates, Generally rough to touch, Host Rock for Lead
Available in Lots of Colors and Patterns, Generally rough to touch, Surfaces are often shiny
Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

More about Talc carbonate and Scoria
Here you can know more about Talc carbonate and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Scoria consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Scoria, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Talc carbonate is Soft and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Talc carbonate vs Scoria. The hardness of Talc carbonate is 1-2 and that of Scoria is 5-6. The types of Talc carbonate are Sedimentary rock whereas types of Scoria are Basaltic Scoria and Andesitic Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Scoria is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Scoria is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Talc carbonate is heat resistant, wear resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
