    The Marl Slate: a model for the precipitation of calcite, dolomite and sulphides in a newly formed anoxic sea (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 34 (1987), S. 0

    ISSN: 1365-3091

    Topics: Geosciences
    Notes: Detailed studies of a new, complete Marl Slate core in South Yorkshire have provided information on isotopic (δ13C, δ18O, δ34S) and geochemical variations (trace elements and C/S ratio) which enable the formulation of a model for carbonate and sulphide precipitation in the Late Permian Zechstein Sea. Calcite and dolomite are intimately associated; the fine lamination, organic character and absence of benthos in the sediments are indicative of anoxic conditions. Lithologically the core can be divided into a lower, predominantly sapropelic Marl Slate (2 m) and an upper Transition Zone (0·65 m) of alternating sapropel and calcite-rich and dolomite-rich carbonates.C/S ratios are 2·22 for the Marl Slate and 1·72 for the Transition Zone respectively, both characteristic of anoxic environments. δ18O in the carbonates shows a large and systematic variation closely mirrored by variations in calcite/dolomite ratio. The results suggest a fractionation factor equivalent to a depletion of 3·8% for 18O and 1·5% for 13C in calcite. The δ34S values of pyrite are isotopically light (mean value = - 32·7%) suggesting a fractionation factor for the Marl Slate of almost 44%, typical of anoxic basins.The results are related to stratification in the early Zechstein Sea. Calcite was precipitated in oxic upper layers above the halocline. Below the oxic/anoxic boundary framboidal pyrite was precipitated, resulting in lower sulphate concentration and elevated Mg/Ca ratio (due to calcite precipitation). As a result of this, dolomite formation occurred below the oxic/anoxic interface, within the anoxic water column and in bottom sediments. Variations in calcite/dolomite ratios, and isotopic variations, are thus explained by fluctuations in the relative level of the oxic/anoxic boundary in the Zechstein Sea.

    Springer
    Wood science and technology 23 (1989), S. 273-279

    Notes: Summary The preservative treatment of four different wood based board materials using an esterified borate applied in the vapour phase was investigated. Under optimum conditions complete impregnation via the board faces was achieved in all boards treated. Board moisture content and treatment time had a major influence on retention and depth of penetration of the borate vapour.

    Notes: [Auszug] A variety of modes of displacement have been put forward for the Great Glen Fault. Some are based on pre-Devonian evidence4'5 and are not considered relevant to our argument. We consider the following three: First, sinistral movements of 200-300 km (ref. 1) or - 500km (ref. 6). ...

    Evidence of rapid changes in the Permian geomagnetic field during the Zechstein marine transgression (1977)

    Notes: [Auszug] Late Palaeozoic palaeomagnetic data are voluminous, largely because of the ubiquity of easily measured red beds and igneous rocks. Within these data there are systematic discrepancies and it has been suggested that the Permian geomagnetic field did not perfectly correspond to an axial dipole. ...

    Notes: [Auszug] To ANY molecular biologist who has the time to reflect, it will no doubt seem surprising that only a decade ago we were (blissfully?) unaware of the existence of the intervening sequences that are present in many of the genes of eukaryotic cells. What seems all the more amazing is how far we have ...

    Effects of propranolol and oxprenolol on the vasoconstrictor response to noradrenaline in the superficial hand vein in man (1978)
    Springer
    European journal of clinical pharmacology 14 (1978), S. 83-85

    Notes: Summary The effects of oxprenolol and propranolol on the venoconstrictor response to noradrenaline were studied in healthy volunteers by measuring superficial dorsal hand vein diameter at a standard congesting pressure. In 8 subjects dose response curves to noradrenaline (20–1280 ng/ml) were obtained with noradrenaline alone, with noradrenaline plus propranolol 10 µg/ml, with noradrenaline plus propranolol 10 µg/ml plus oxprenolol 3 µg/ml and with noradrenaline plus propranolol 13 µg/ml according to a double blind balanced randomised design. Propranolol 10 µg/ml significantly (P〈0.05) potentiated the vasoconstrictor response to noradrenaline and the addition of oxprenolol significantly (P〈0.05) reversed the potentiation giving a response similar to that seen with noradrenaline alone. The higher concentration of propranolol did not produce further potentiation, the response being similar to that obtained with the lower concentration of propranolol. It is suggested that the effect of oxprenolol may be attributable to alpha blocking properties, to partial beta agonism or to its membrane stabilising properties.
