Where Can Conglomerates Form?

Conglomerates form by the consolidation and lithification of gravel. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks.

How conglomerate are formed?

Conglomerate. Conglomerate is made up of rounded pebbles (>2mm) cemented together. They are formed from sediment deposited by fast-flowing rivers or by waves on beaches.

Where is conglomerate most likely to be formed?

They commonly form as rock-fall and debris flow deposits along cliffs, and underground along faults or where caves collapse. Because water is ubiquitous on the Earth's surface, conglomerates are far more common than sedimentary breccias.
