Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

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.
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

More about Talc carbonate and Ignimbrite
Here you can know more about Talc carbonate and Ignimbrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Ignimbrite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Ignimbrite includes Apatite, Biotite, Calcite, Chlorite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Ignimbrite, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Ignimbrite is available in beige, black, brown, grey, pink, white colors. Appearance of Talc carbonate is Soft and that of Ignimbrite is Dull, Vesicular and Foilated. Properties of rock is another aspect for Talc carbonate vs Ignimbrite. The hardness of Talc carbonate is 1-2 and that of Ignimbrite is 4-6. The types of Talc carbonate are Sedimentary rock whereas types of Ignimbrite are Pyroclastic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Ignimbrite is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Ignimbrite is 0.20 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 Ignimbrite is heat resistant, impact resistant, pressure resistant, wear resistant.
