Definition
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From French schiste, Greek skhistos i.e. split
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Formation
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Blueschist and Conglomerate Properties
Know all about Blueschist and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Blueschist belongs to Metamorphic Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Blueschist is Foliated whereas that of Conglomerate is Clastic. Blueschist appears Dull and Banded and Conglomerate appears Shiny and Rounded. The luster of Blueschist and Conglomerate is dull. Blueschist is available in blue, bluish - grey, purple, shades of blue colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones and that of Conglomerate are cemetery markers, in aquifers, tombstones.
