5.1 Formation
Variolites are a group of dark green basic igneous rocks that exhibit pale colored spots on weathered surfaces that give them a pockmarked appearance.
Larvikite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Variolite vs Larvikite 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 Variolite and Larvikite Reserves. 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. Larvikite is an igneous rock and a variety of monzonite, notable for the presence of thumbnail-sized crystals of feldspar. 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 Variolite vs Larvikite information and Variolite vs Larvikite characteristics in the upcoming sections.

Variolite vs Larvikite 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. Variolite vs Larvikite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Variolite and Properties of Larvikite. Learn more about Variolite vs Larvikite in the next section. The interior uses of Variolite include Floor tiles, Flooring, Homes, Hotels and Kitchens whereas the interior uses of Larvikite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Variolite and Larvikite, they have various applications in construction industry. The uses of Variolite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Larvikite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.

More about Variolite and Larvikite

Here you can know more about Variolite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock.
