Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

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.
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

All about Norite and Mudstone Properties
Know all about Norite and Mudstone properties here. All properties of rocks are important as they define the type of rock and its application. Norite belongs to Igneous Rocks while Mudstone belongs to Sedimentary Rocks.Texture of Norite is Phaneritic whereas that of Mudstone is Clastic. Norite appears Veined and Shiny and Mudstone appears Rough and Dull. The luster of Norite is not available while that of Mudstone is dull. Norite is available in dark grey to black colors whereas Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. The commercial uses of Norite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Mudstone are creating artwork, pottery.
