Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Claystone and Conglomerate Properties
Know all about Claystone and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Claystone and Conglomerate belong to Sedimentary Rocks.Texture of Claystone is Clastic whereas that of Conglomerate is Clastic. Claystone appears Rough and Dull and Conglomerate appears Shiny and Rounded. The luster of Claystone and Conglomerate is dull. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Claystone are pottery and that of Conglomerate are cemetery markers, in aquifers, tombstones.
