Formation

Formation

Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Breccia vs Pumice Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Breccia and Pumice Reserves. Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Breccia vs Pumice information and Breccia vs Pumice characteristics in the upcoming sections.

Breccia vs Pumice Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Breccia vs Pumice characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Breccia and Properties of Pumice. Learn more about Breccia vs Pumice in the next section. The interior uses of Breccia include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Breccia and Pumice, they have various applications in construction industry. The uses of Breccia in construction industry include As dimension stone, Construction aggregate, Landscaping, Roadstone and that of Pumice include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks.

More about Breccia and Pumice

Here you can know more about Breccia and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Breccia and Pumice consists of mineral content and compound content. The mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Breccia vs Pumice, the texture, color and appearance plays an important role in determining the type of rock. Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors whereas, Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Breccia is Layered, Banded, Veined and Shiny and that of Pumice is Vesicular. Properties of rock is another aspect for Breccia vs Pumice. The hardness of Breccia is 7 and that of Pumice is 6. The types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia whereas types of Pumice are Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Breccia is white while that of Pumice is white, greenish white or grey. The specific heat capacity of Breccia is 0.84 kJ/Kg K and that of Pumice is 0.87 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Breccia is heat resistant, impact resistant, pressure resistant, wear resistant whereas Pumice is impact resistant, pressure resistant.
