Ludlow to Přidoli age Old Red Sandstone alluvial to marginal marine deposits of the Anglo-Welsh Basin record a punctuated molasse shed from an inverted, transient catchment area. An erosional low-gradient sequence-bounding pediment surface was creat

Studies of the behaviour of different types of present-day river channels with regard to sediment transport and depositional processes enable interpretation of fluvial deposits throughout the stratigraphic record. Early studies concentrated on the de

Metal mining used to be a major source of heavy-metal contamination for river systems and in England and Wales affected areas exceed 4000 km2. Under flooding conditions, heavy metals stored in riverbeds and floodplains can be remobilised and become s

Distal environs of the Ludlow-age Trichrug Formation from south central Wales (UK) detail deposition on the outer fringe of an ephemeral debris flow-dominated alluvial fan. Debrites and subordinate sheetflood deposits are interbedded with sporadic th

The Upper Silurian/Lower Devonian Old Red Sandstone of the southwest Wales is dominated by fluvial sediments deposited in a mud-rich, low gradient, dryland setting that, apart from rare finds of fish head shields and spines, is lacking in fossil faun

The Late-glacial and Holocene environmental history of the Gordano Valley, North Somerset, UK has been reconstructed using pollen, sediment particle size and mineralogical analyses and radiocarbon dating. A Devensian sediment ridge across the valley

The Early Devonian Conigar Pit Sandstone Member (CPSM) of the Freshwater West Formation (Lower Old Red Sandstone, Lochkovian age) at Freshwater West in south Wales comprises a heterolithic, predominantly alluvial suite (mudstones, fine to coarse-grai

The recent growth in the use of microfossil-based transfer functions in late-Quaternary sea-level reconstructions reflects their potential to accurately quantify palaeo sea-level changes. This study details the development of a diatom-based sea-level

Mudrocks are a prominent feature of many ancient dryland successions but they are not always a product of the settling out of suspension load. From studies of the late Silurian–early Devonian Old Red Sandstone mudrocks of South Wales it has been sh
