Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities
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
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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.
