The coarse-grained sedimentary rock made up of angular fragments is called a breccia.

Breccia is typically formed from the accumulation of angular rock fragments that are cemented together. The angularity of its fragments indicates that they have not been transported far from their source, which is a characteristic feature distinguishing breccia from other sedimentary rocks like conglomerate, which consists of rounded fragments. The formation of breccia can occur in various geological environments, including fault zones, landslide areas, and volcanic regions, where massive amounts of material are broken and deposited. This rock type is significant in sedimentology and geology, providing insights into the conditions of its formation and the geological history of the area.
