Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.
