Breccia is a type of rock characterized by the presence of angular, fragmented clasts that are cemented together by a matrix material. This rock forms through the accumulation and lithification of substantial amounts of rock debris, which, due to limited transport or energy, maintain sharp, irregular edges. Its formation typically involves processes such as the fracturing of bedrock or the deposition of angular fragments within cavities or bedding planes. The composition of the breccia can vary widely, reflecting the original source rock, and its structure provides insight into the depositional environment, which is generally associated with catastrophic or high-energy sedimentary events.
