Formation

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

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.
