Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Nepheline Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

All about Conglomerate and Nepheline Syenite Properties
Know all about Conglomerate and Nepheline Syenite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Nepheline Syenite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Nepheline Syenite is Granular. Conglomerate appears Shiny and Rounded and Nepheline Syenite appears Banded and Foilated. The luster of Conglomerate is dull while that of Nepheline Syenite is greasy to dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Nepheline Syenite is available in brown, buff, cream, green, grey, pink, white colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Nepheline Syenite are cemetery markers, creating artwork.
