Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
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
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.

Basanite vs Cataclasite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Basanite vs Cataclasite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Cataclasite. Learn more about Basanite vs Cataclasite in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Cataclasite include Decorative aggregates and Homes. Due to some exceptional properties of Basanite and Cataclasite, they have various applications in construction industry. The uses of Basanite in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Basanite and Cataclasite
Here you can know more about Basanite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Cataclasite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase 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 Basanite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Basanite is Glassy or Pearly and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Basanite vs Cataclasite. The hardness of Basanite is 7 and that of Cataclasite is 3-4. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite 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 Basanite is white while that of Cataclasite is black. The specific heat capacity of Basanite is 0.74 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.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
