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.

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 colourless, 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 Not Available whereas types of Talc carbonate are Not Available. 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 Not Available 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.
