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.

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.
