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
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster

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.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

All about Cataclasite and Anthracite Properties
Know all about Cataclasite and Anthracite properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite and Anthracite belong to Metamorphic Rocks.Texture of Cataclasite is Clastic whereas that of Anthracite is Amorphous, Glassy. Cataclasite appears Dull and Banded and Anthracite appears Veined or Pebbled. The luster of Cataclasite is vitreous while that of Anthracite is shiny. Cataclasite is available in brown, green, white, yellow colors whereas Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
