Definition
Jasperoid is a rare, peculiar type of metasomatic alteration of rocks
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix

Archaeological Significance
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.
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Jasperoid and Cataclasite
Here you can know more about Jasperoid and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jasperoid and Cataclasite consists of mineral content and compound content. The mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Jasperoid vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Jasperoid is available in black, brown, green, grey, pink, white colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Jasperoid is Glassy or Pearly and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Jasperoid vs Cataclasite. The hardness of Jasperoid is 3.5-4 and that of Cataclasite is 3-4. The types of Jasperoid are - whereas types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jasperoid is white while that of Cataclasite is black. The specific heat capacity of Jasperoid is 0.92 kJ/Kg K and that of Cataclasite is 0.84 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 Cataclasite is heat resistant, impact resistant, pressure resistant.
