    Sedimentation and palaeoenvironments of Late Cretaceous crater-lake deposits in Bushmanland, South Africa (1986)

    Notes: A large diameter borehole core from an epiclastic kimberlite remnant on the farm Stompoor in the Prieska district, Cape Province, contains a continuous 76 m section of fossiliferous sediments interpreted as having accumulated within a crater-lake during the Late Cretaceous. Three distinct facies associations reflect depositional processes that prevailed in offshore areas of the original lake. Facies Association A: matrix-supported pebble conglomerates comprising a chaotic assemblage of pyroclastic, basement and country rocks set in a fine-grained matrix. Flat, non-erosional basal surfaces with ‘frozen’ rip-up clasts, the protrusion of matrix-supported clasts above the upper surfaces and a direct relationship between maximum clast size and bed thickness suggest deposition from debris flows that originated subaerially on pyroclastic talus cones surrounding the crater. Facies Association B: alternating thin beds of matrix-supported granule conglomerate, structureless fine-grained sandstone and parallel laminated mudrock. Small fining-upward sequences within these beds are comparable to turbidite Bouma Tade, Tde. Numerous partings display petrified fish and frog skeletons, as well as bivalve, gastropod and ostracode shells, leaf impressions, insect wings and a possible bird bone. These beds were deposited by thin debris-flows and turbidity underflows interspersed with periods of ‘pelagic’ sedimentation. Facies Association C: microlaminated mudstone beds containing scattered ‘dropstone lapilli’. The lamination is imparted by alternating Ca-rich/Ca-poor layers which may reflect climatic seasonality. They are interpreted as the result of seasonally influenced suspension settling through a thermally stratified water column.Short-term periodicities in conglomerate bed thicknesses are interpreted as the result of successive block caving of a slump scar giving rise to several debris flows from the same source area. Seismic shock from nearby volcanism may have simultaneously triggered slumps on both subaerial and subaqueous slopes. Dropstone lapilli in Type C beds and the preponderance of load casting in Type B beds support this interpretation. An estimate of the time span involved in accumulating 76 m of crater lake sediments based on the possible seasonal imprint of Type C beds gives a figure of some 220,000 yr.

    The culture of benthic marine algae in the laboratory and the field (1970)
    Springer

    Description / Table of Contents: Summary 1. Growth and development of algae from spores has been observed in the laboratory (Menai Bridge) and under field conditions at Ravenspoint (West coast of Anglesey). Attempts were made to culture all main components of the sub-littoral flora. Spore material was obtained from spores allowed to settle onto plastic slides in the laboratory sea water system and from spores settled on slides stationed in the field. 2. Attention was given to the summer annual species and, in particular, to those members of the Nemalionales (Rhodophyceae) which have incompletely known life histories. In these plants, the tetrasporic phase during which reduction division normally takes place, has so far been undetected in the field. The plants are represented by the cystocarpic phase of the life cycle only. 3. The fate of the carpospores of these species were of particular interest. The spores of the annual species were cultivated under a number of regimes of irradiation and temperature. Sporelings from laboratory culture were transferred to the field in November, 2 months after settlement. Both in laboratory and field, the form of development of the cultures were similar until May of the following year. Then the field cultures developed structures which may represent the tetrasporangia of the alternate phase. These structures failed to develop in the laboratory cultures after 3 years. 4. The results of these experiments illustrate that care must be taken in interpreting results of laboratory cultures of algae, in particular in regard to their life histories.
    Notes: Kurzfassung Der Aspekt der sublitoralen Algenvegetation vor der Küste von Ravenspoint (Westküste von Anglesey) wird entscheidend von der mechanischen Wellenwirkung, der Trübung des Wassers und der Sedimentierung geprägt. Auf den durch die Winterstürme stark verlagerten und abgescheuerten Steinen in 4 m Tiefe dicht unter der Küste kann sich erst ab April-Mai eine üppige Vegetation annueller Arten entwickeln. In 9 m Tiefe überstehen nur derbere Formen wieChondrus oderFurcellaria die winterliche Sedimentablagerung. Hier stellen sich in den Somermonaten außer den auch in 4 m vorkommenden Arten einjährige Rotalgen wieNaccaria, Halarachnion, Scinaia undHelminthora ein. Zur Klärung ihrer Ökologie und Lebensgeschichte wurden Steine ins Laboratorium verbracht und der sich entwickelnde Aufwuchs untersucht, außerdem Kulturen dieser Arten auf Objektträgern im Laboratorium und am natürlichen Standort verglichen. Besonderes Interesse verdienen Vertreter der Nemalionales (Rhodophyceae), in deren Lebenszyklus bisher nur die karposporentragende Phase bekannt ist. Zwei Monate alte Kulturen vonNaccaria wurden im November aus dem Laboratorium an ihren natürlichen Standort gebracht. Nach gleichartiger Entwicklung bis zum Mai des folgenden Jahres bildeten sie Strukturen, die vielleicht der tetrasporentragenden Phase entsprechen. Solche Stadien wurden während der dreijährigen Kultur im Laboratorium nicht beobachtet. Daher ist eine kritische Beurteilung der an Laboratoriumskulturen erhaltenen Ergebnisse angezeigt, besonders bei der Untersuchung des Lebenszyklus von Algen. Die Zellenanordnung junger Corallinaceen-Krusten zeigte charakteristische Unterschiede, die vielleicht als taxonomische Kriterien verwertbar sind.

    Retention indices in supercritical fluid chromatography on a polystyrene-divinylbenzene column (1988)

    Notes: Summary The application of alkylarylketones and n-alkanes as retention index scale standards in supercritical fluid chromatography has been examined using a packed polystyrene-divinylbenzene column. The two scales gave comparable results but the alkylarylketone scale gave comparable results but the alkylarylketone scale was considered to have a wider application as it could also be used when modifiers were added to the mobile phase. The changes in the retention indices of a number of aromatic test compounds were used to compare the selectivity of the separation under different temperature and pressure conditions and in the presence of modifiers.

    Notes: This paper is an expanded version of that delivered at the recent Sixth International Symposium on Finite Element Methods in Flow Problems, Antibes, France. It begins by reviewing the role of the finite element method (FEM) in turbulent flow simulation during recent years. The difficulties in incorporating sufficiently general descriptions of turbulence (i.e. two-equation models) into successful finite-element-based Navier-Stokes codes are examined and analysed in some depth. Current progress by various workers in overcoming these difficulties is reviewed and, by concentrating on one particular approach, it is demonstrated that the FEM has now matured into a powerful and flexible tool for solving two-dimensional turbulent flows of industrial complexity. The applications presented highlight those features which render the FEM attractive in this field (viz., minimal false diffusion, arbitrary local refinement, boundary fitting capabilities and non-structured grids). Finally, the prospects and challenges for the future are briefly discussed. In particular, the urgency and difficulty of constructing a competitive three-dimensional capability which preserves these features is examined.
