Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

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.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

More about Talc carbonate and Oolite
Here you can know more about Talc carbonate and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Oolite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Talc carbonate is Soft and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Talc carbonate vs Oolite. The hardness of Talc carbonate is 1-2 and that of Oolite is 3-4. The types of Talc carbonate are Sedimentary rock whereas types of Oolite are Pisolitic Oolite and Oncolitic Oolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Oolite is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Oolite is 0.65 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 Oolite is heat resistant, wear resistant.
