Definition
Theralite is a plutonic hylocrystalline igneous rock consisting of augite, olivine, calcic plagioclase and nepheline
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
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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

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