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

Features
Available in lots of colors, Generally rough to touch, Very fine grained rock

Archaeological Significance
Formation
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.
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.

Oolite vs Talc carbonate 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. Oolite vs Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oolite and Properties of Talc carbonate. Learn more about Oolite vs Talc carbonate in the next section. The interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Oolite and Talc carbonate, they have various applications in construction industry. The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping and that of Talc carbonate include Source of calcium.
More about Oolite and Talc carbonate
Here you can know more about Oolite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Talc carbonate consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Sedimentary Rocks. When we have to compare Oolite vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas, Talc carbonate is available in grey, white colors. Appearance of Oolite is Rounded and Rough and that of Talc carbonate is Soft. Properties of rock is another aspect for Oolite vs Talc carbonate. The hardness of Oolite is 3-4 and that of Talc carbonate is 1-2. The types of Oolite are Pisolitic Oolite and Oncolitic Oolite whereas types of Talc carbonate are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oolite and Talc carbonate is white. The specific heat capacity of Oolite is 0.65 kJ/Kg K and that of Talc carbonate is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Oolite is heat resistant, wear resistant whereas Talc carbonate is heat resistant, wear resistant.
