Journal ArticleDOI
Lagoonal sedimentation and fluctuating salinities in the Vectis Formation (Wealden Group, Lower Cretaceous) of the Isle of Wight, southern England
TL;DR: In this article, a cyclicity of four principal facies on which a strong asymmetry has been imprinted by erosional events is described, and the biota, principally associated with lithofacies 2 and 3 (as shelly partings and coquinas), can be grouped into five molluscan associations which range from freshwater to quasi-marine.
Journal ArticleDOI
Milankovitch-scale palaeoclimate changes in pale–dark bedding rhythms from the Early Cretaceous (Hauterivian and Barremian) of eastern England and northern Germany
Jörg Mutterlose,Alastair Ruffell +1 more
TL;DR: In this article, a wide range of palaeontological and geochemical analyses show conclusively how bedding rhythms, developed in the Milankovitch band, are the result of a palaeoclimate change.
Journal ArticleDOI
The Vöhrum section (northwest Germany) and the Aptian/Albian boundary
Jörg Mutterlose,André Bornemann,Friedrich Wilhelm Luppold,Hugh G. Owen,Alastair Ruffell,W Weiss,David Wray +6 more
TL;DR: In this article, a detailed multidisciplinary study has been made of a new section at Vohrum (clay pit no. 4) with respect to its content of calcareous nannofossils, benthic foraminifera, planktonic finetail animals, ostracods, ammonites, as well as its clay mineralogy, gamma ray signature and tuff geochemistry.
Journal ArticleDOI
Palaeoclimate control on sequence stratigraphic patterns in the late Jurassic to mid-Cretaceous, with a case study from Eastern England
Alastair Ruffell,Peter F. Rawson +1 more
TL;DR: Sediment supply is a fundamental control on the architecture of sedimentary sequences, and the volume of sediment being transported into the basin of deposition is strongly dependent on both the nature of the weathering regime in the hinterlands, and on runoff.
Journal ArticleDOI
Firmgrounds – key surfaces in the recognition of parasequences in the Aptian Lower Greensand Group, Isle of Wight (southern England)
Alastair Ruffell,Grant D. Wach +1 more
TL;DR: Aptian Lower Greensand Group exposures in the cliffs of the Isle of Wight (southern England) display a consistent coarsening-up cyclicity on the scale of centimetres to tens of metres.
