Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Norite 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 Basanite and Norite
Here you can know more about Basanite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Norite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Norite, 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, Norite is available in dark grey to black colors. Appearance of Basanite is Glassy or Pearly and that of Norite is Veined and Shiny. Properties of rock is another aspect for Basanite vs Norite. Hardness of Basanite and Norite is 7. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Norite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite is white while that of Norite is black. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Norite is Not Available. 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 Norite is impact resistant, pressure resistant, wear resistant.
