Definition
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
Monzogranite is a type of igneous rock and belongs to biotite granite rocks that are considered to be the final fractionation product of magma

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.
Monzogranite 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 Monzogranite 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 Monzogranite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Variolite and Properties of Monzogranite. Learn more about Variolite vs Monzogranite in the next section. The interior uses of Variolite include Floor tiles, Flooring, Homes, Hotels and Kitchens whereas the interior uses of Monzogranite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Variolite and Monzogranite, 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 Monzogranite include As dimension stone.
More about Variolite and Monzogranite
Here you can know more about Variolite and Monzogranite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Variolite and Monzogranite consists of mineral content and compound content. The mineral content of Variolite includes Olivine, Plagioclase, Pyroxene and mineral content of Monzogranite includes Apatite, Biotite, Hornblende, Microcline, Perthite, Plagioclase, Quartz, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Variolite vs Monzogranite, the texture, color and appearance plays an important role in determining the type of rock. Variolite is available in black, brown, light to dark grey colors whereas, Monzogranite is available in black, grey, orange, pink, white colors. Appearance of Variolite is Dull and Soft and that of Monzogranite is Veined or Pebbled. Properties of rock is another aspect for Variolite vs Monzogranite. The hardness of Variolite is 6 and that of Monzogranite is 6-7. The types of Variolite are Not Available whereas types of Monzogranite are Muscovite-Biotite-Metagranite, Muscovite-Metagranite, Schollen-Metagranite and Biotite-Metagranite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Variolite is white to grey while that of Monzogranite is white. The specific heat capacity of Variolite is 0.84 kJ/Kg K and that of Monzogranite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Variolite is heat resistant, pressure resistant, wear resistant whereas Monzogranite is heat resistant, wear resistant.
