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
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

More about Boninite and Basanite
Here you can know more about Boninite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Basanite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Basanite , 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, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Boninite is Dull and Soft and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Boninite vs Basanite . Hardness of Boninite and Basanite is 7. The types of Boninite are Basalt whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite and Basanite is white.
