Dense Welding Caused by Volatile Resorption
Read preview
Abstract: Welding of pyroclastic rocks is generally thought to occur by mechanical expulsion of interstitial gas from a deposit as it compacts under its own weight. We propose here that volatile resorption and compression can also be important factors...
Denudation Rates for the Southern Drakensberg Escarpment, SE Africa, Derived from In-Situ-Produced Cosmogenic 36cl: Intial Results
Read preview
Cosmogenic ^sup 36^Cl concentrations in basalt samples from the Drakensberg escarpment on the SE African passive margin give quantitative estimates of denudation and scarp retreat rates. Over the 10^sup 4^-10^sup 6^ year timespan addressed by these data,...
Eocene Inversion History of the Sandown Pericline, Isle of Wight, Southern England
Read preview
Abstract: Study of the composition and distribution of derived lithoclast and fossil suites collected from the Selsey, Barton and Becton Formations in Whitecliff Bay, Isle of Wight has enabled a detailed reconstruction of Mid-Late Eocene uplift of 500...
First 40ar/39ar Age Constraints for the Caledonian Evolution of the Trans-European Suture Zone in NE Germany
Read preview
Abstract: From three Rijgen boreholes (G14, R(igen 5, Loissin 1) across the Caledonian deformation front four Lower Palaeozoic slate samples and three detrital muscovite concentrates from associated sandstones have been analysed by ^sup 40^Ar/^sup 39^Ar...
Palaeomagnetic Correlation of the Upper Triassic of Somerset, England, with Continental Europe and Eastern North America
Read preview
Abstract: Three Normal and three Reversed palaeomagnetic polarity zones were identified in the exposed 67 m section of Mercia Mudstone at St Audrie's Bay, Somerset, which has been regarded as being of Norian age on limited biostratigraphic evidence....
Platinum-Group Mineralization in the Rum Layered Intrusion, Scottish Hebrides, UK
Read preview
Abundant and diverse platinum-group minerals occur in the Rum layered intrusion, Inner Hebrides, Scotland. Platinum-group minerals are associated with chromite-rich horizons in both the Eastern and Western layered series, and are enclosed by Ni- and...
Proxy Records of Climate Change in the UK over the Last Two Millennia: Documented Change and Sedimentary Records from Lakes and Bogs
Read preview
Abstract: This project of collaborative research (project Ila of the NERC TIGGER programme-Terrestrial Initiative in Global Geological Environmental Research) into the climatic history of the late Holocene used a variety of techniques, both tested and...
The Chronology of Palaeoenvironmental Changes during the Last Glacial-Holocene Transition: Towards an Event Stratigraphy for the British Isles
Read preview
Abstract: The overall aim of the TIGGER Ilb project is to increase our understanding of the manner and rates by which ecosystems responded to climate changes during the Last Glacial-Holocene transition. Success in this venture requires better constrained...
The Last Climatic Cycle at Kopais, Central Greece
Read preview
Abstract: Thick lacustrine sequences from southern Europe provide an opportunity to derive continuous records where the chronostratigraphical position of pre-Holocene stages can be determined with increased confidence. Here, high-resolution sediment...
TIGGER: NERC-Stimulated Research into the Geological Perspective of Terrestrial Global Environmental Research
Read preview
Abstract: TIGGER was devised to study the geological factors relevant to the NERC TIGER programme (Terrestrial Initiative in Global Environmental Research). The geological initiative concerned itself with the collection of high resolution data to solve...
