Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite

Etymology
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball
From the first syllable of the Finnish words Ii-vaara, Iijoki, &c. commonly used geographical names in Finland, and the Gr. Xiflos, a stone

Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Ijolite 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 Ijolite Properties
Know all about Conglomerate and Ijolite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Ijolite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Ijolite is Earthy, Granular. Conglomerate appears Shiny and Rounded and Ijolite appears Banded and Foilated. The luster of Conglomerate is dull while that of Ijolite is greasy to dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Ijolite 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 Ijolite are cemetery markers, creating artwork.
