What is the difference between sedimentary breccia and conglomerate




















The angular particle shape reveals that they have not been transported very far transport wears the sharp points and edges of angular particles into rounded shapes. 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.

In arid and semiarid areas, the precipitation of mineral cements in shallow sediments or soils can result in the formation of extensive rock units known as " caliche. Limestone Breccia: A breccia that contains clasts of multiple types of limestone.

Specimen is about four inches ten centimeters across. 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.

In breccia the large particles are angular in shape, but in conglomerate the particles are rounded. The particle shape reveals a difference in how far the particles were transported. Near the outcrop where the fragments were produced by mechanical weathering, the shape is angular.

However, during transport by water away from the outcrop, the sharp points and edges of those angular fragments are abraded and rounded. The rounded particles would form a conglomerate.

Talus Slopes: Scene of a mountain environment where talus, the angular mechanical weathering debris that might form breccia, is produced in abundance. Breccia has many compositions. Its composition is mainly determined by the rock and mineral material that the angular fragments were produced from. The climate of the source area can also influence composition. 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. Often a breccia will contain many types of angular rock fragments.

These are known as polymict breccias or polymictic breccias. Breccia can be any color. The color of the matrix or cement along with the color of the angular rock fragments determine its color. Breccia can be a colorful rock, as shown in the photos on this page. Material on the fan was weathered from the mountains in the background and transported a very short distance.

The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Breccia include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Interior decoration. Due to some exceptional properties of Conglomerate and Breccia, they have various applications in construction industry.

The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Breccia include As dimension stone, Construction aggregate, Landscaping, Roadstone. Here you can know more about Conglomerate and Breccia.

The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Breccia consists of mineral content and compound content.

You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Breccia, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors.

Properties of rock is another aspect for Conglomerate vs Breccia. The hardness of Conglomerate is and that of Breccia is 7. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.

The streak of Conglomerate and Breccia is white. The specific heat capacity of Conglomerate is 0. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc. Conglomerate is heat resistant whereas Breccia is heat resistant, impact resistant, pressure resistant, wear resistant. A softUsvista venture! These are sedimentary rock types that are so similar that many question their classification into two different rock types. However, there are differences between conglomerate and breccia that will be highlighted in this article.

The first fact one needs to understand when discussing these two rock types is that, all the difference between Conglomerate and Breccia stems from the way they are created. So, let us see how these rocks are created among other things. It is easy to distinguish between breccias and conglomerates with naked eyes as grains are much large and easily seen with naked eyes.

When the grain size is less than 2 mm, it becomes difficult to see them with naked eyes, and then the rock is simply categorized as sandstone. 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 get formed when host rocks break, and their debris are not transported to any far off place. This means that these rocks form when original rocks break and re-accumulate to make pieces that are angular in texture. Situations that often lead to the formation of breccias are landslides, impact craters, fault zones, explosions, and so on.
