Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

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 17th century, because of its greasy feel and use like a soap

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

All about Conglomerate and Soapstone Properties
Know all about Conglomerate and Soapstone properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Soapstone belongs to Metamorphic Rocks.Texture of Conglomerate is Clastic whereas that of Soapstone is Polished. Conglomerate appears Shiny and Rounded and Soapstone appears Dull, Banded and Foilated. The luster of Conglomerate is dull while that of Soapstone is greasy. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Soapstone is available in black, black to grey, green, grey colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Soapstone are cemetery markers, creating artwork, gemstone, jewelry, manufacture of soap, solvents, dyes, plastics and fibres, production of lime, source of magnesia (mgo).
