Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

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.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

More about Norite and Eclogite
Here you can know more about Norite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Eclogite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Eclogite, 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, Eclogite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Norite is Veined and Shiny and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Norite vs Eclogite. The hardness of Norite is 7 and that of Eclogite is 3.5-4. The types of Norite are Not Available whereas types of Eclogite are Not Available. 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 Eclogite is white. The specific heat capacity of Norite is Not Available and that of Eclogite 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 Eclogite is heat resistant.
