| 62 | AGG | Agglomerate - A type of pyroclastic-rock. In the Rock Classification Scheme, it is a pyroclastic-rock in which more than 75% of the pyroclastic fragments exceed 64 mm in size. Agglomerate and pyroclastic-breccia are separated according to the relative proportion of blocks (angular fragments exceeding 64 mm) and bombs (rounded fragments exceeding 64 mm): if bombs dominate over blocks the rock is agglomerate. It is the consolidated equivalent of bomb-tephra or block-bomb-tephra.

| 63 | AGGE | Aggregate - A type of artificial deposit. In the building industry, aggregate is a range of mineral substances, for example sand, gravel, crushed rock, stone, slag and other minerals which, when cemented, forms concrete, mortar, mastic, and plaster. Uncemented, it can be used as a bulk material in road-making and ballast.
