Definition
Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar
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
Blue Granite is an igneous rock which is a variety of Larvikite and is known mainly for the presence of thumbnail-sized crystals of feldspar.
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 Blue Granite and Cataclasite
Here you can know more about Blue Granite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Blue Granite and Cataclasite consists of mineral content and compound content. The mineral content of Blue Granite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon 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 Igneous Rocks. When we have to compare Blue Granite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Blue Granite is available in black, brown, light to dark grey, white colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Blue Granite is Shiny and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Blue Granite vs Cataclasite. The hardness of Blue Granite is 6-7 and that of Cataclasite is 3-4. The types of Blue Granite are Granite 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 Blue Granite is white while that of Cataclasite is black. The specific heat capacity of Blue Granite is 0.79 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.Blue Granite is heat resistant, impact resistant, pressure resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
