Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.

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