Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Ijolite 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.

Limestone vs Ijolite 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. Limestone vs Ijolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Ijolite. Learn more about Limestone vs Ijolite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Ijolite include Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Limestone and Ijolite, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Ijolite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Limestone and Ijolite
Here you can know more about Limestone and Ijolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Ijolite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Ijolite, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Ijolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Limestone is Rough and Banded and that of Ijolite is Banded and Foilated. Properties of rock is another aspect for Limestone vs Ijolite. The hardness of Limestone is 3-4 and that of Ijolite is 5.5-6. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Ijolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone and Ijolite is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Ijolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Limestone is pressure resistant whereas Ijolite is heat resistant, impact resistant, wear resistant.
