Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Harzburgite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Claystone and Harzburgite
Here you can know more about Claystone and Harzburgite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Harzburgite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Harzburgite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Harzburgite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Harzburgite is available in dark greenish - grey colors. Appearance of Claystone is Rough and Dull and that of Harzburgite is Rough and Shiny. Properties of rock is another aspect for Claystone vs Harzburgite. The hardness of Claystone is 3.5-4 and that of Harzburgite is 5.5-6. The types of Claystone are Not Available whereas types of Harzburgite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Harzburgite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Harzburgite is 1.25 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Harzburgite is heat resistant, pressure resistant, wear resistant.
