Definition
Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock
  
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

Formation
Hornblendite 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.
  
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.

Hornblendite 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. Hornblendite vs Cataclasite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hornblendite and Properties of Cataclasite. Learn more about Hornblendite vs Cataclasite in the next section. The interior uses of Hornblendite include Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration and Kitchens whereas the interior uses of Cataclasite include Decorative aggregates and Homes. Due to some exceptional properties of Hornblendite and Cataclasite, they have various applications in construction industry. The uses of Hornblendite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Hornblendite and Cataclasite
Here you can know more about Hornblendite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Cataclasite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite 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 Hornblendite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Hornblendite is Foliated and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Hornblendite vs Cataclasite. The hardness of Hornblendite is 6-7 and that of Cataclasite is 3-4. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite 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 Hornblendite is white to grey while that of Cataclasite is black. The specific heat capacity of Hornblendite is Not Available and that of Cataclasite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
