Breccia – an overview
Breccia is commonly used for clastic sedimentary rocks composed of large sharp-angled fragments embedded in a fine-grained matrix of smaller particles or mineral cement. The breccia generated by folding, faulting, magmatic intrusions, and similar forces is called tectonic breccia..
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. Rocks formed by sticking together pieces of previous rocks (clasts) are called clastic rocks. There are two types of clastic rock

Classification of fault breccias and related fault rocks
Instead we propose that fault breccia should be defined, as with sedimentary breccia, primarily by grain size: with at least 30% of its volume comprising clasts at least 2 mm in diameter. To subdivide fault breccias, we advocate the use of textural terms borrowed from the cave-collapse literature – crackle, mosaic and chaotic breccia – with bounds at 75% and 60% clast content.
Diamictite or a matrix-supported breccia from Tenerife. This mixture is located in the Las Cañadas caldera and probably is a result of the formation process of the caldera. Width of view 1.7 meters. References 1. Flint, R. F. (1960). Diamictite, a substitute term for

Answer: TRUE Bloom’s Taxonomy: Analysis 8) Coal is a sedimentary rock that is made of organic matter.

Sedimentary Rocks and the Rock Cycle

 · PDF 檔案Major Rock Types Igneous rocks are formed by the cooling of molten magma or lava near, at, or below the Earth’s surface. Sedimentary rocks are formed by the lithification of inorganic and organic sediments deposited at or near the Earth’s surface.
Clastic Sedimentary Rocks
Clastic sedimentary rocks form by weathering processes which break down rocks into pebble, sand, or clay particles by exposure to wind, ice, and water. Clastic and nonclastic sedimentary rocks are the only members of the rock family that contain fossils as well as indicators of the climate (ripple marks, mudcracks and raindrops) that was present when the rock was formed.

how does granite turn into breccia?
 · A breccia is just a sedimentary rock in which the angular fragments are cemented together. It is like a conglomerate but instead of rounded particles as in the conglomerate, the particles are angular. One way in which a granite can turn into a breccia is along the
Is pumice intrusive or extrusive?
 · 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
Sedimentary Rock Classification
 · Living creatures can help chemicals become sedimentary rocks. Limestone is an example. Organic Sedimentary Rocks The bodies of organisms can make a sedimentary rock. Plant bodies are lithified to become coal. When shells are cemented together they make
