Detailed explanation-1: -Breccia is a term most often used for clastic sedimentary rocks that are composed of large angular fragments (over two millimeters in diameter). The spaces between the large angular fragments can be filled with a matrix of smaller particles or a mineral cement that binds the rock together.

Detailed explanation-2: -Breccia (/ˈbrɛtʃiə, ˈbrɛʃ-/) is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix.

Detailed explanation-3: -“Igneous, ” “flow, ” or “pyroclastic” breccias are rocks composed of angular fragments of preexisting igneous rocks of pyroclastic debris ejected by the volcanic blast or pyroclastic flow.

Detailed explanation-4: -breccia, lithified sedimentary rock consisting of angular or subangular fragments larger than 2 millimetres (0.08 inch). It differs from a conglomerate, which consists of rounded clasts.
