Definition
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains
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

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Variolites are a group of dark green basic igneous rocks that exhibit pale colored spots on weathered surfaces that give them a pockmarked appearance.

Jadeitite 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. Jadeitite vs Variolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jadeitite and Properties of Variolite. Learn more about Jadeitite vs Variolite in the next section. The interior uses of Jadeitite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Variolite include Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Jadeitite and Variolite, they have various applications in construction industry. The uses of Jadeitite in construction industry include As dimension stone, Cutting tool, Knives and that of Variolite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Jadeitite and Variolite
Here you can know more about Jadeitite and Variolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Variolite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Variolite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Variolite, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, colourless, green, grey, white colors whereas, Variolite is available in black, brown, light to dark grey colors. Appearance of Jadeitite is Rough and Dull and that of Variolite is Dull and Soft. Properties of rock is another aspect for Jadeitite vs Variolite. The hardness of Jadeitite is 3-5 and that of Variolite is 6. The types of Jadeitite 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 Jadeitite is white, greenish white or grey while that of Variolite is white to grey. The specific heat capacity of Jadeitite is 0.95 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.Jadeitite is heat resistant, water resistant whereas Variolite is heat resistant, pressure resistant, wear resistant.
