Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

All about Conglomerate and Schist Properties
Know all about Conglomerate and Schist properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Schist belongs to Metamorphic Rocks.Texture of Conglomerate is Clastic whereas that of Schist is Foliated, Platy. Conglomerate appears Shiny and Rounded and Schist appears Layered and Shiny. The luster of Conglomerate is dull while that of Schist is shiny. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Schist is available in black, blue, brown, dark brown, green, grey, silver colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Schist are used in aquariums, writing slates.
