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. British Geological Survey Research Report RR/99/06, section 4.2 and fig. 4.
