The impact breccia page Introduction. A breccia is a clastic sedimentary rock composed of angular clasts in a consolidated matrix. Breccias can be produced in several geologic processes: tectonic breccia, volcanic breccia (eruption breccia, vent breccia), sedimentary breccia (e.g., rock fall breccia), collapse breccia (e.g., in karst areas).

Breccia After deposition the fragments are bound together by a mineral cement or by a matrix of smaller particles that fills the spaces between the fragments. Breccia and conglomerate are very similar rocks. They are both clastic sedimentary rocks composed of particles larger than two millimeters in diameter.The difference is in the shape of the large particles.eologists 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. A few more uses of the word are given below.

- Clastic sedimentary rocks are classified based on the size of the mineral grains (Table 6.1). If the grains are large (>2 mm, i.e., a coarse-grained texture) and rounded, the rock name is conglomerate. Breccia has coarse and angular grains. For coarse-grained clastic sedimentary rocks, a prefix is put before the

Limestone usually is composed of finer grained material of calcite origin, such as sea shells, or precipitates of calcite origin.uartzite is the metamorphic product of sandstone. During metamorphism, intense heat and/or pressure cause the quartz grains contained in the sandstone grow and recrystallize, … interlocking together creating Quartzite. 4 people found this useful.

- This occurs in the areas ofsouthern KwaZulu-Natal, (south of 30° 30') where the name Ecca Shale Formation is preferred.

About Sedimentary Rocks Clastic Sedimentary Rocks. The most common set of sedimentary rocks consist of the granular materials that occur in sediment. Sediment mostly consists of surface minerals —quartz and clays—that are made by the physical breakdown and chemical alteration of rocks.f gravel or pebbles are part of the sediment, the rock that forms is conglomerate. If the rock is broken and recemented together it is called breccia. See examples of all these in the Sedimentary Rock Index. It's worth noting that some rocks commonly lumped in the igneous category are actually sedimentary.

- They can form by explosive fragmentation during volcanism, by fracturing along faults and as products of mass wasting. Breccias of sedimentary origin are closely related to mass-wasting processes, and the detrital clasts have moved only a short distance from their bedrock source. 8. Distinguish between the two categories of chemical sedimentary rocks.

- The sedimentary rock, limestone, consists of particles of calcite, traces of other minerals, and organic residues. Calcite is a carbonate mineral (CaCO3) that is precipitated from seawater effectively by respiration processes in marine plants and animals.exture (the size, shape, and distribution of particles that collectively constitute the rock) is a function of the geologic processes related to a rock's formation. For instance, granite is an intrusive igneous rock in which the mineral grains display visible crystal surfaces.

Which of the following sedimentary rocks is a chemical rock? Best Answer: None of the choices is a chemical rock. Shale and sandstone are clastic sedimentary rocks. Halite is an evaporite mineral. It could be considered a chemical mineral, but it is not a rock. Breccia is a series of angular rock fragments. Most geologists use the term breccia to describe rock fragments originating from tectonic processes, and much more rarely from sedimentary processes.

Sedimentary rock Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth 's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle and accumulate or minerals to precipitate from a solution.Particles that form a sedimentary rock by accumulating are called sediment.Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by water, wind, ice, mass movement or glaciers which are called agents of denudation.ost sedimentary rocks contain either quartz (especially siliciclastic rocks) or calcite (especially carbonate rocks). In contrast to igneous and metamorphic rocks, a sedimentary rock usually contains very few different major minerals.
