Quizplus · Accepted Answer

Breccia is a rock composed of broken fragments of minerals or rock cemented together by a fine-grained matrix that can be similar to or different from the composition of the fragments. The key characteristic of breccia is its angular fragments, which indicates that the rock fragments were not transported far from their source before being cemented together. The size specification of >70 mm also fits the description of breccia, as it implies the fragments are coarse.
