Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Norite and Suevite Properties
Know all about Norite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Norite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Norite is Phaneritic whereas that of Suevite is Earthy. Norite appears Veined and Shiny and Suevite appears Banded. The luster of Norite is while that of Suevite is earthy. Norite is available in dark grey to black colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Norite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
