1.1 Definition

Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals

Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

5.1 Formation

Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Pumice vs Conglomerate 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 Pumice and Conglomerate Reserves. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix. 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 Pumice vs Conglomerate information and Pumice vs Conglomerate characteristics in the upcoming sections.

Pumice vs Conglomerate 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. Pumice vs Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pumice and Properties of Conglomerate. Learn more about Pumice vs Conglomerate in the next section. The interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Pumice and Conglomerate, they have various applications in construction industry. The uses of Pumice in construction industry include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks and that of Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.

More about Pumice and Conglomerate

Here you can know more about Pumice and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Conglomerate consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Pumice vs Conglomerate, the texture, color and appearance plays an important role in determining the type of rock. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors whereas, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Pumice is Vesicular and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Pumice vs Conglomerate. The hardness of Pumice is 6 and that of Conglomerate is 2-3. The types of Pumice are Scoria whereas types of Conglomerate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pumice and Conglomerate is white, greenish white or grey. The specific heat capacity of Pumice is 0.87 kJ/Kg K and that of Conglomerate is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pumice is impact resistant, pressure resistant whereas Conglomerate is heat resistant.
