✦ Synopsis

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

Intraplate volcanism in the Central Indian Ocean Basin (CIOB) has been of much interest, since this tectonically young and structurally complex basin holds signatures of at least one major plate reorganisation at 65 š 5 Ma; and two major plate boundary structural deformations occurring at 54:5 š 3 M

## Abstract Inversion of the Lower Palaeozoic Welsh Basin during the Early to Mid‐Devonian is generally thought to have been achieved by a combination of approximately co‐axial shortening and transcurrent movement along major faults to produce a strongly partitioned transpressional strain. However,
