Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).

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

All about Conglomerate and Nephelinite Properties
Know all about Conglomerate and Nephelinite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Nephelinite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Nephelinite is Aphanitic. Conglomerate appears Shiny and Rounded and Nephelinite appears Skeletal. The luster of Conglomerate is dull while that of Nephelinite is vitreous to metallic. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Nephelinite is available in black, brown, colourless, green, grey, white colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Nephelinite are creating artwork, soil conditioner, source of magnesia (mgo).
