Definition
Icelandite belongs to volcanic igneous rocks which is rich in iron and belongs to andesite rock
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

Archaeological Significance
Formation
Icelandite 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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Due to some exceptional properties of Icelandite and Boninite, they have various applications in construction industry. The uses of Icelandite in construction industry include Cobblestones, Construction aggregate, For road aggregate 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 Icelandite and Boninite
Here you can know more about Icelandite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Icelandite and Boninite consists of mineral content and compound content. The mineral content of Icelandite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Icelandite vs Boninite, the texture, color and appearance plays an important role in determining the type of rock. Icelandite is available in bluish - grey, grey, pink, yellow colors whereas, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Icelandite is Dull and Soft and that of Boninite is Dull and Soft. Properties of rock is another aspect for Icelandite vs Boninite. Hardness of Icelandite and Boninite is 7.
