Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
  
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

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

More about Oolite and Claystone
Here you can know more about Oolite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Claystone consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt 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 Oolite vs Claystone, 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, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Oolite is Rounded and Rough and that of Claystone is Rough and Dull. Properties of rock is another aspect for Oolite vs Claystone. The hardness of Oolite is 3-4 and that of Claystone is 3.5-4. The types of Oolite 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 Oolite and Claystone is white. The specific heat capacity of Oolite is Not Available 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.Oolite is heat resistant, wear resistant whereas Claystone is heat resistant, impact resistant.
