“…4). Stewart et al (1991) indicated that C-phase ostracods are not found in the highest part of the Vectis Formation (highest Shepherds Chine Member), the fauna being entirely S-phase, although no details were given. The present author examined a sample from the highest Vectis Formation at Sandown Bay, 0.25m below the contact with the Atherfield Bone Bed, where only very rare specimens of Sternbergella cornigera were found.…”

“…The remainder of the Perna Member contains evidence of shallow, oligohaline to miohaline conditions, probably associated with the lagoonal and interdistributary bays (Kerth & Hailwood, 1988;Stewart et al, 1991;Hart et al, 1991). The marine incursion into the region took place during the obsoletum Subzone, and brought with it both macro and micro faunas which rapidly occupied the newly formed environmental niches.…”

“…The Shepherd's Chine Member is interpreted as a shallow, storm influenced lagoon deposit (Stewart, et al 1991), on the basis of sedimentary structures. Its cyclicity reflects intermittent increases in the fluvial input and flooding events into the lagoon, and it has been suggested that these may be climatically controlled (Insole, Daley and Gale, 1998).…”

The effect of environmental change on early Aptian ostracods faunas in the Wessex Basin, southern England

A major phase of transgression in the Wessex Basin (southern England) during the earliest Aptian resulted in the collapse of the generally fresh water Barremian environment and the initiation of the marine mileu.Cypridea-rich faunas low in the Shepherd's Chine Member (Vectis Formation), were gradually replaced by faunas dominated by Sternbergella cornigera, Mantelliana mantelli and Theriosynoecum fittoni. This change is interpreted as indicating that salinities had passed from fresh-oligohaline to meso-and pliohaline and that ephemoral water bodies were replaced by more widespread, permanent, lagoonal waters. The ostracods from the highest part of the Vectis Formation, appear to be heralding the major transgression that was about to engulf the Wessex Basin.

The earliest Aptian marine transgression across southern England resulted in the collapse of the generally freshwater Barremian environment and the initiation of marine mileux. Salinities passed from fresh-oligohaline to meso-and pliohaline, reaching fully marine conditions during the obsoletum Subzone (P. fissicostus Zone).Newly formed environmental niches were rapidly occupied by ostracod associations.

“…Its constituent three members are defined (from the base, these are the Cowleaze Chine, Barnes High and Shepherd's Chine members) and can be easily traced on this coastline (Daley and Stewart, 1979;Stewart, 1981b;Stewart et al, 1991;Wach and Ruffell, 1991). The Vectis Formation shows considerably more evidence than the preceding Wessex Formation of very shallow lacustrine or lagoonal deposition with fluctuating salinities.…”

The geological history of the Isle of Wight: an overview of the ‘diamond in Britain's geological crown’

The geology of the Isle of Wight has attracted both the amateur and professional geologist alike for well over two centuries. It presents a cornucopia of things geological and offers a window into the fascinating story of the geological history and landscape development of southern England, as well as an important teaching resource for all levels of study from primary education through to academic research.This paper provides a geological framework and a summary of the history of research as context for the papers in this issue can be placed. Inevitably, it can only offer a précis of the huge amount of information available, but it is hoped will also give added impetus to further investigation of the literature or, indeed, new research.The island offers a field workshop for topics such as lithostratigraphy, sequence stratigraphy, tectonics and climate change; studies that are becoming ever more international in their influence. There are 15 Sites of Special Scientific Interest designated because of their geological importance and a number of these are internationally significant.After a brief discussion on the concealed geology, this paper concentrates on an outline of the near-surface geology on the coast and inland, and introduces a different view on the structure of the Cretaceous and Palaeogene strata. The enigmatic Quaternary deposits are discussed particularly with reference to the development of the Solent River, human occupation and climate change.
