| 201 | BBTPH | Bomb-block-tephra - A type of pyroclastic-sediment. In the Rock Classification Scheme, it is a pyroclastic-sediment in which the average size of more than 75% of the pyroclastic fragments exceeds 64 mm. Block-tephra, bomb-block-tephra, block-bomb-tephra, and bomb-tephra are separated according to the relative proportion of blocks (angular fragments exceeding 64 mm) and bombs (rounded fragments exceeding 64 mm): if between 50% and 75% of all pyroclastic fragments bigger than 64 mm are blocks the sediment is bomb-block-tephra. It is the unconsolidated equivalent of pyroclastic-breccia.

| 211 | BGCCOL | Boghead-cannel-coal - A type of sapropelic-coal. It is a transitional stage between cannel-coal and boghead-coal in which miospores dominate over alginite.

| 212 | BGCOL | Boghead-coal - A type of sapropelic-coal. It is similar to cannel-coal but browner and rich in alginite with very few miospores. It appears unstratified on macroscopic examination. Microscopic examination shows that boghead-coal consists of alginite and very finely dispersed inertinite and vitrinite. The proportion of alginite can vary widely. Boghead-coal is sometimes referred to as torbanite. This term is not recommended for usage.
