Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Variolites are a group of dark green basic igneous rocks which exhibit pale colored spots, or spherules, especially on weathered surfaces, that give them a pockmarked appearance

Conglomerate vs Variolite 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. Conglomerate vs Variolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Variolite. Learn more about Conglomerate vs Variolite in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Variolite include Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Conglomerate and Variolite, 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 Variolite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Conglomerate and Variolite
Here you can know more about Conglomerate and Variolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Variolite consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Variolite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Variolite, 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, Variolite is available in black, brown, light to dark grey colors. Appearance of Conglomerate is Shiny and Rounded and that of Variolite is Dull and Soft. Properties of rock is another aspect for Conglomerate vs Variolite. The hardness of Conglomerate is 2-3 and that of Variolite is 6. The types of Conglomerate are Not Available whereas types of Variolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate is white while that of Variolite is white to grey. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Variolite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Variolite is heat resistant, pressure resistant, wear resistant.
