Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

All about Conglomerate and Sandstone Properties
Know all about Conglomerate and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Sandstone belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Sandstone is Clastic, Granular, Rough. Conglomerate appears Shiny and Rounded and Sandstone appears Rough. The luster of Conglomerate and Sandstone is dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Sandstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
