Conglomerate is a clastic sedimentary rock that contains large (greater than two millimeters in diameter) rounded clasts.
sedimentary rock, composed of rounded, mostly water born, gravel-size pebbles in a finer sediment matrix. Conglomerate is the consolidated equivalent of gravel. The size of the fragments refers to a mean particle diameter above 2 mm (more than 50% of the particles have to be larger than 2 mm), below this grain size: sandstone. conglomerates are composed of rounded fragments (contrary to breccias).
