Breccia (/ ˈ b r ɛ tʃ i ə, ˈ b r ɛ ʃ-/) is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix. The word has its origins in the Italian language, in which it means "rubble". [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 are filled with a matrix of smaller particles and a mineral cement that binds the rock together.
Breccia is a type of sedimentary rock that plays a significant role in the field of geology. It is characterized by its distinctive appearance, which consists of angular rock fragments and clasts that are cemented together.
Breccia rocks, characterized by their angular fragments cemented together, are a type of sedimentary rock with a diverse range of origins and compositions. One fascinating aspect of breccia rocks is the variations in their composition.
As a clastic sedimentary rock, breccia is, by definition, composed of rock and/or mineral fragments. These fragments are broken pieces of older rocks that have been transported to their new place of deposition (likely very nearby) to form a new rock.
Breccia is a sedimentary rock made up of angular particles over two millimeters in diameter (clasts) with the spaces between the particles filled with smaller particles and mineral cement (matrix). The word "breccia" has an Italian origin and means "stone made of cemented gravel."
Breccias are very important host rocks for mineralisation, not only because,of the large surface area they make available for water-rock interaction and the fact that they represent zones of high permeability, but some of the processes of brecciation such as hydraulic fracturing can closely related to the process of mineralisation.
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. A brief treatment of breccias follows.
