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
Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite
Origin
Swiss Alps, Europe
Romania and Moldova, Europe
Discoverer
Michael Tellinger
Unknown
Etymology
From the Italian word cataclasi
From Dacia, a province of the Roman Empire which lay between the Danube River and Carpathian Mountains where the rock was first described

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.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

More about Cataclasite and Dacite
Here you can know more about Cataclasite and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Dacite consists of mineral content and compound content. The mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz and mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all . When we have to compare Cataclasite vs Dacite, 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, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Cataclasite is Dull and Banded and that of Dacite is Vesicular. Properties of rock is another aspect for Cataclasite vs Dacite. The hardness of Cataclasite is 3-4 and that of Dacite is 2-2.25. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite.
