Formation
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.
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.

Aplite vs Norite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Aplite vs Norite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Norite. Learn more about Aplite vs Norite in the next section. The interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Norite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Aplite and Norite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Norite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Aplite and Norite
Here you can know more about Aplite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Norite consists of mineral content and compound content. The mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Aplite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Aplite is available in black, grey, orange, pink, white colors whereas, Norite is available in dark grey to black colors. Appearance of Aplite is Veined or Pebbled and that of Norite is Veined and Shiny. Properties of rock is another aspect for Aplite vs Norite. The hardness of Aplite is 6.5 and that of Norite is 7. The types of Aplite are Not Available 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 Aplite is white while that of Norite is black. The specific heat capacity of Aplite is 0.79 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.Aplite is heat resistant, wear resistant whereas Norite is impact resistant, pressure resistant, wear resistant.
