Conglomerate and Soapstone


Definition

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

Formation

Formation
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.   
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Soapstone and Conglomerate Properties

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