A conglomerate is a type of sedimentary rock defined by the cemented accumulation of rounded fragments, or clasts. These clasts can range widely in size and composition, potentially including pebbles, cobbles, or pieces of previously formed bedrock. The formation process involves deposition in high-energy environments, such as ancient fluvial systems or coastal areas, followed by lithification, which binds the diverse fragments together within a surrounding finer-grained matrix. The resulting rock structure is thus heterogeneous, exhibiting visible layers and cemented inclusions that characterize its physical composition.
