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.

2020年1月17日 · 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 …

2018年6月1日 · A brief literature review on the breccias of contrasting origin, their diagnostic signatures along with related terminologies is presented here. The importance of individual breccia types and their geological implication has also been reviewed.

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.

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.
