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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

More about Jasperoid and Claystone
Here you can know more about Jasperoid and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jasperoid and Claystone consists of mineral content and compound content. The mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Jasperoid vs Claystone, 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, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Jasperoid is Glassy or Pearly and that of Claystone is Rough and Dull. Properties of rock is another aspect for Jasperoid vs Claystone. Hardness of Jasperoid and Claystone is 3.5-4. The types of Jasperoid are Not Available whereas types of Claystone 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 Claystone is white. The specific heat capacity of Jasperoid is 0.92 kJ/Kg K and that of Claystone 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 Claystone is heat resistant, impact resistant.
