Formation
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.
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 Jasperoid and Talc carbonate
Here you can know more about Jasperoid and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jasperoid and Talc carbonate consists of mineral content and compound content. The mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides 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 Jasperoid vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas, Talc carbonate is available in colourless, grey, white colors. Appearance of Jasperoid is Glassy or Pearly and that of Talc carbonate is Soft. Properties of rock is another aspect for Jasperoid vs Talc carbonate. The hardness of Jasperoid is 3.5-4 and that of Talc carbonate is 1-2. The types of Jasperoid 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 Jasperoid and Talc carbonate is white. The specific heat capacity of Jasperoid is 0.92 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.Jasperoid is heat resistant, pressure resistant, wear resistant whereas Talc carbonate is heat resistant, wear resistant.
