Norite and Conglomerate
Definition
Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

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