Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Basanite and Andesite
Here you can know more about Basanite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Andesite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Basanite is Glassy or Pearly and that of Andesite is Dull and Soft. Properties of rock is another aspect for Basanite vs Andesite. Hardness of Basanite and Andesite is 7. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite and Andesite is white. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Andesite is 2.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Andesite is heat resistant, pressure resistant, wear resistant.
