Definition
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
Theralite is a plutonic hylocrystalline igneous rock consisting of augite, olivine, calcic plagioclase and nepheline

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

More about Boninite and Theralite
Here you can know more about Boninite and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Theralite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Theralite, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, green, grey colors whereas, Theralite is available in dark grey to black colors. Appearance of Boninite is Dull and Soft and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Boninite vs Theralite. Hardness of Boninite and Theralite is 7. The types of Boninite are Basalt whereas types of Theralite are Teschenite and Essexite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite and Theralite is white. The specific heat capacity of Boninite is 0.84 kJ/Kg K and that of Theralite is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Boninite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Theralite is impact resistant, pressure resistant, wear resistant.
