Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

Limestone vs Boninite 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 Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Boninite. Learn more about Limestone vs Boninite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Limestone and Boninite, 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 Boninite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Limestone and Boninite
Here you can know more about Limestone and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Boninite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Boninite, 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, Boninite is available in bluish - grey, brown, colourless, green, grey colors. Appearance of Limestone is Rough and Banded and that of Boninite is Dull and Soft. Properties of rock is another aspect for Limestone vs Boninite. The hardness of Limestone is 3-4 and that of Boninite is 7. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Boninite 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 Boninite is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Boninite 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 Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
