Brecciation is a geological term that refers to the process of breaking up of rocks into angular fragments, and these fragments get cemented together again. Other synonyms for brecciation include fragmentation, disintegration, fracture, and shattering. Brecciation can occur naturally, for instance, due to tectonic activity, or it can result from man-made activities like blasting and quarrying. The term can also describe the rocks that have undergone brecciation, in which case they are referred to as breccias. A brecca is a rock composed of fragments of other rocks held together by a matrix, and it may be formed by brecciation or other processes. The study of brecciation is essential in the field of geology, as it helps geologists understand the history and formation of rocks.
