Definition
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

More about Granite and Basanite
Here you can know more about Granite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granite and Basanite consists of mineral content and compound content. The mineral content of Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Granite vs Basanite , the texture, color and appearance plays an important role in determining the type of rock. Granite is available in black, grey, orange, pink, white colors whereas, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Granite is Veined or Pebbled and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Granite vs Basanite . The hardness of Granite is 6-7 and that of Basanite is 7. The types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite.
