Formation

Formation

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

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Boninite and Icelandite Reserves. 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. Icelandite belongs to volcanic igneous rocks which is rich in iron and belongs to andesite rock. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Boninite vs Icelandite information and Boninite vs Icelandite characteristics in the upcoming sections.

Boninite vs Icelandite Characteristics
