Earth material Sedimentary rock Clastic rock
Breccia is a clastic sedimentary rock composed of various sized visible pieces of other rock, cemented together by the processes of lithification. The pieces of rock that are … visible are angular fragments, meaning they have somewhat jagged edges. Breccia is an inorganic land-derived sedimentary rock. It is clastic (fragmental), but not foliated. Breccia is composed of mostly quartz, feldspar, and clay minerals; it may … contain fragments of other rocks and minerals.

Breccia is a type of rock which is composed of broken fragments of minerals. It is commonly used as an aggregate and as dimension stone for decoration of walls and floors. Fault Breccia: Broken rock found in the contact area between two fault blocks and produced by movement of the fault. Flow Breccia: A lava texture produced when the crust of a lava flow is broken and jumbled during movement. Igneous Breccia: A term used for a rock composed angular fragments of igneous rocks. Flow breccia and pyroclastic breccia could be called igneous breccia. Impact Breccia: A deposit of angular rock debris produced by the impact of an asteroid or other cosmic body. See an article about impactites Sedimentary [edit]. Sedimentary breccia is a type of clastic sedimentary rock which is made of angular to subangular, randomly oriented clasts of other sedimentary rocks. A conglomerate, by contrast, is a sedimentary rock composed of rounded fragments or clasts of pre-existing rocks. Both breccia and conglomerate are composed of fragments averaging greater than 2 millimetres (0.079 in) in size. Earth material Sedimentary rock Clastic rock. Sedimentary breccia. A breccia (coarse-grained clastic rock composed of angular broken rock fragments held together by a mineral cement or a fine-grained matrix) formed by sedimentary processes. This category is also used for breccia.  Most breccias are a mix of rock fragments and mineral grains. The type of rock that the fragments were produced from is often used as an adjective when referring to the rock. Some examples: sandstone breccia, limestone breccia, granite breccia, chert breccia, basalt breccia and others. Flow Breccia: A lava texture produced when the crust of a lava flow is broken and jumbled during movement. Igneous Breccia: A term used for a rock composed angular fragments of igneous rocks. Flow breccia and pyroclastic breccia could be called igneous breccia. Geologists have been very generous in their use of the word breccia.. It is common to hear the term used when referring to a rock or rock debris made up of angular fragments. Although it is mainly used for rocks of sedimentary origin it can be used for other types of rocks. Flow Breccia: A lava texture produced when the crust of a lava flow is broken and jumbled during movement. Igneous Breccia: A term used for a rock composed angular fragments of igneous rocks. Flow breccia and pyroclastic breccia could be called igneous breccia. Breccia is a name given to clastic sedimentary rocks that are formed by clinging together of a large number of angular fragments. Breccia is formed with the space between the fragments either filled by smaller fragments or mineral cement, which is responsible for holding the rock together. • Breccias have angular fragments. In other words, Breccia has angular clasts. • Fragments are much more rounded in conglomerates. In other words, Conglomerate has rounded clasts. Breccia is a rock formed from angular gravel and boulder-sized clasts cemented together in a matrix. The angular nature of the clasts indicates that they have not been transported very far from their source. There are several modes of formation for breccia.
