Definition
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
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite
Origin
Swiss Alps, Europe
Finland, Europe

Etymology
From the Italian word cataclasi
From the first syllable of the Finnish words Ii-vaara, Iijoki, &c. commonly used geographical names in Finland, and the Gr. Xiflos, a stone

Formation
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.
Ijolite 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.

You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Ijolite, the texture, color and appearance plays an important role in determining the type of rock. Cataclasite is available in brown, green, white, yellow colors whereas, Ijolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Cataclasite is Dull and Banded and that of Ijolite is Banded and Foilated. Properties of rock is another aspect for Cataclasite vs Ijolite. The hardness of Cataclasite is 3-4 and that of Ijolite is 5.5-6. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Ijolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Cataclasite is black while that of Ijolite is white. The specific heat capacity of Cataclasite is Not Available and that of Ijolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Cataclasite is heat resistant, impact resistant, pressure resistant whereas Ijolite is heat resistant, impact resistant, wear resistant.
