What rocks are in conglomerate?
Conglomerate is a sedimentary rock made of rounded pebbles and sand that is usually held together (cemented) by silica, calcite or iron oxide. It is a stone similar to sandstone but the rock particles are rounded or angular gravel rather than sand.
What is volcanic conglomerate?
A water-deposited conglomerate containing more than 50% volcanic material, esp. coarse pyroclastics.
What type of rock is glacial conglomerate?
Conglomerates are clastic sedimentary rock that contains mostly pebble-size rounded clasts. The spaces between the clasts are generally filled with smaller particles and/or chemical cement that then binds and formed the rock matrices together.

What causes conglomerate rock?
Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. It takes a strong water current to transport and produce a rounded shape on particles this large. Wind transport is unlikely to produce a conglomerate.
