context_page_description: Breccia is a type of rock formed of broken fragments of minerals or rock cemented together by a fine-grained matrix. The matrix may be similar to or different from the composition of the fragments.
  Rocks formed by sticking together pieces of previous rocks are called clastic rocks. There are two types of clastic rock: conglomerates and breccias. What divides these two categories is the amount of rounding. The particles that make up conglomerates are well rounded, whereas in breccias they are angular.
