Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Borolanite is a variety of Nepheline Syenite and belongs to igneous rocks and contains nepheline-alkali feldspar pseudomorphs which occur as conspicuous white spots in the dark rock matrix

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