Within the Welsh Basin, proximal volcanism of Wenlock age is virtually unknown. However, two vitroclastic tuffs and a turbiditic tuffaceous mudstone have been discovered lying along the eastern side of the basin. Their sources have not been located, but the tuffaceous mudstone and the older tuff are both of riccartonensis Zone age and may be the products of the same event. The younger tuff is of early ludensis Zone age. All three occur in association with bentonites and represent, or were involved in, sedimentary instability. © 1998 John Wiley & Sons, Ltd.
