Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents

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