5.1 Formation

Picrite 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.

Picrite vs Boninite 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 Picrite and Boninite Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. 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. 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 Picrite vs Boninite information and Picrite vs Boninite characteristics in the upcoming sections.
