Breccia (/ ˈbrɛtʃiə / BRETCH-ee-ə or / ˈbrɛʃiə / BRESH-ee-ə, Italian: [ˈbrettʃa]; Italian for 'breach') 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 …

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.

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.

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 [1] is a type of rock formed of broken fragments of minerals or rock cemented together by a fine-grained matrix. [2] The matrix may be similar to or different from the composition of the fragments.

The meaning of BRECCIA is a rock composed of sharp fragments embedded in a fine-grained matrix (such as sand or clay).

Conglomerates (rounded clasts) and breccias (angular clasts) are composed of >50% gravel-sized particles (>2 mm).

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.

What Is Breccia? Breccia is a type of rock that consists of angular fragments (or pieces) of other rocks. These fragments are usually cemented together by a natural cementing material, such as calcite or quartz. Breccia can also form from the accumulation and welding of debris from volcanoes or glaciers.
