Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite

Formation
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.
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

More about Norite and Hawaiite
Here you can know more about Norite and Hawaiite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Hawaiite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Hawaiite, the texture, color and appearance plays an important role in determining the type of rock. Norite is available in dark grey to black colors whereas, Hawaiite is available in black, brown, light to dark grey colors. Appearance of Norite is Veined and Shiny and that of Hawaiite is Dull and Soft. Properties of rock is another aspect for Norite vs Hawaiite. The hardness of Norite is 7 and that of Hawaiite is 6. The types of Norite are Ultramafic intrusive rock whereas types of Hawaiite are Volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Norite is black while that of Hawaiite is . The specific heat capacity of Norite is 0.52 kJ/Kg K and that of Hawaiite 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.Norite is impact resistant, pressure resistant, wear resistant whereas Hawaiite is heat resistant, pressure resistant, wear resistant.
