Breccia (/ ˈ b r ɛ tʃ i ə / BRETCH-ee-ə or / ˈ b r ɛ ʃ i ə / BRESH-ee-ə, Italian:; Italian for 'breach') is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix.

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 …

2023年9月4日 · 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.

2018年6月1日 · Breccia is a term generally used for an enigmatic rock group that consists of a variety of individual mineral grains or broken fragments of rocks, often very angular and cemented together by a fine grain matrix, and sometimes glassy matrix which may or may not be similar to the composition of rock fragments (Fisher, 1961, Schmid, 1981, Laznicka,...

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.

2025年3月27日 · Breccia stone has long been used in architecture and design, from ancient Roman columns to modern luxury baths. But what exactly is breccia, and how can a stone restoration craftsman identify and work with it effectively? Let’s dive into both the geological and practical aspects of this fascinating material. Geological Description.

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. For full treatment, see sedimentary rock: Conglomerates and …

2020年1月17日 · Breccia is a sedimentary rock made of angular particles called clasts and a mineral cement matrix. Breccia is formed by different processes and can be classified based on how it forms and its composition. Breccia is used for making sculptures, architectural elements, and sometimes as a fill material for roads.

Breccia is a clastic sedimentary rock made from many different sizes of angular grains, many of which are gravel-sized or larger. These grains are fragments of other rocks, bound together by cement which is typically silica or calcite.

Breccia (Italian: breach) is a rock composed of angular fragments of rocks or minerals in a matrix (or cementing material) that may be similar to or different in composition from the fragments. Breccia rocks may have a variety of different origins, as indicated by their names.
