โฆ Synopsis
The collection of papers in this volume results from a joint meeting of the Tectonic Studies Group and the British Sedimentological Research Group of the Geological Society of London, held at the University College of Wales, Aberystwyth on 10-12 April 1986. About half the papers presented at that meeting were offered for publication. A report of the full proceedings has appeared in the Journal of the Geological Society (Fitches and Woodcock 1986) as have abstracts of all the contributions.
The stimulus for the conference was the recent upsurge in structural and sedimentological research in Wales, following and partly stimulated by new work on Welsh volcanic rocks (reviews by Allen 1982; Bevins et al. 1984; Kokelaar et al. 1984). The papers here reflect the breadth as well as the quantity of the activity, particularly in previously underresearched areas such as the Mid Welsh Late Ordovician to Early Silurian sedimentary rocks.

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
