Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

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.
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Norite vs Diabase 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. Norite vs Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Norite and Properties of Diabase. Learn more about Norite vs Diabase in the next section. The interior uses of Norite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Norite and Diabase, they have various applications in construction industry. The uses of Norite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Norite and Diabase
Here you can know more about Norite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Diabase consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Diabase, 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, Diabase is available in dark grey to black colors. Appearance of Norite is Veined and Shiny and that of Diabase is Vesicular. Properties of rock is another aspect for Norite vs Diabase. Hardness of Norite and Diabase is 7. The types of Norite are Not Available whereas types of Diabase are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Norite and Diabase is black. The specific heat capacity of Norite is Not Available and that of Diabase is Not Available. 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 Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
