  • Redox Changes in the Deep Shelf of the East Baltic Basin in the Aeronian and Early Telychian (Early Silurian)
    Proc. Estonian Acad. Sci. Geol., 2004, 53, 2, 94–124 Redox changes in the deep shelf of the East Baltic Basin in the Aeronian and early Telychian (early Silurian) Enli Kiipli Institute of Geology at Tallinn University of Technology, Estonia pst. 7, 10143 Tallinn, Estonia; [email protected] Received 27 March 2003, in revised form 11 February 2004 Abstract. Aeronian black shales and overlying Telychian greenish-grey and red claystones of the deep shelf of the East Baltic Basin indicate different synsedimentary redox conditions of the bottom water of the sea. In the Aeronian, the primary bioproductivity rise caused accumulation of organic- rich black shale in deep shelf and formation of microcrystalline limestone with chertification, chert nodules, and barite in shoreward areas. In the early Telychian, the bioproductivity decreased, as concluded from the absence of indicators of high primary bioproductivity in the Aeronian. The suggested mechanism regulating primary bioproductivity and oxygen content of bottom waters of deep shelf was a change from wind-induced upwelling in the Aeronian to downwelling in the Telychian. The sedimentation rate did not influence the change in the redox regime of the deep shelf sediment, as it was low for both the Aeronian and Telychian. Key words: Aeronian, Telychian, East Baltic deep shelf, redox conditions, up- and downwellings. INTRODUCTION Differences in lithology, mineralogy, and rock chemistry evidence changes at the Aeronian–Telychian boundary. The changes concern sea water chemistry and early diagenesis of sediments with implication on hydrodynamic and atmospheric circulation, and palaeogeography. The area of investigation is southwest Estonia and west Latvia, which form a central, deeper part of the Palaeozoic East Baltic basin, treated here as the deep shelf.

  • Subsidence and Tectonics in Late Precambrian and Palaeozoic Sedimentary Basins of Southern Norway
    Subsidence and Tectonics in Late Precambrian and Palaeozoic Sedimentary Basins of Southern Norway KNUT BJØRLYKKE Bjørlykke, K. 1983: Subsidence and tectonics in Late Precambrian sedimentary basins of southern Norway. Norges geol. Unders. 380, 159-172. The assumption that sedimentary basins approach isostatic equilibrium provides a good foundation for modelling basin subsidence based on variables such as cooling rates (thermal contraction), crustal thinning, eustatic sea-level changes and sedimen tation. The Sparagmite basin of Central Southern Norway was probably formed by crustal extension during rifting. During Cambrian and Ordovician times the Oslo Region was rather stable part of the Baltic Shield, reflected in slow epicontinental sedimentation. The Bruflat Sandstone (Uppermost Llandovery) represents the first occurrence of a rapid clastic influx, reflecting a pronounced basin subsidence. This change in sedimentation is believed to be related to the emplacement of the first Caledonian nappes in the northern part of the Oslo Region, providing a nearby source for the sediments and resulting in subsidence due to nappe loading. The underlying Palaeozoic sequence was detached along the Cambrian Alum Shale in front of the Osen Nappe. Devonian sedimentation was characterised by vertical tectonics and some of the Devonian basins, such as the Hornelen Basin, may be related to listric faulting rather than strike-slip fractures. The Permian sediments of the Oslo Graben were probably overlain by Triassic and possibly also by Jurassic sediments during post-rift subsidence. K. Bjørlykke, Geologisk Institutt, Avd. A, Allégt. 41, N-5014 Bergen-Univ. Norway. Introduction Sedimentary basins are very sensitive recorders of contemporaneous tectonic movements. Their potential as a key to the understanding of the tectonic history of a region has, however, not always been fully utilized.

Further distribution or reproduction in any format is prohibited without the permission of the copyright holder. ABSTRACT Trilobites from the Ludlow and Přídolí of England and Wales are described. A total of 15 families; 36 genera and 53 species are documented herein, including a new genus and seventeen new species; fourteen of which remain under open nomenclature. Most of the trilobites in the British late Silurian are restricted to the shelf, and predominantly occur in the Elton, Bringewood, Leintwardine, and Whitcliffe groups of Wales and the Welsh Borderland. The Elton to Whitcliffe groups represent a shallowing upwards sequence overall; each is characterised by a distinct lithofacies and fauna. The trilobites and brachiopods of the Coldwell Formation of the Lake District Basin are documented, and are comparable with faunas in the Swedish Colonus Shale and the Mottled Mudstones of North Wales. Ludlow trilobite associations, containing commonly co-occurring trilobite taxa, are defined for each palaeoenvironment.

These new data constrain timing of orogenic events and help See table of contents understand the origin of the cover rock depocenters. Detrital zircon data generally confirm suggested ages of the formations sampled. Zircon grains with ages of ca. 430 Ma in both depocenters, only slightly older than their host Publisher(s) rocks, were probably derived from the earliest volcanic eruptions in the Eastport-Mascarene belt. Their presence indicates that unnamed CMAM Atlantic Geoscience Society sandstone units may be as young as Pridoli and their absence from the Appleton Ridge and Digdeguash formations suggests that these formations are ISSN older than initial Eastport-Mascarene volcanism. Detrital and volcanic zircon ages confirm a Late Cambrian to Middle Ordovician age for the Miramichi 0843-5561 (print) succession and date Miramichi volcanism at 469.3 ± 4.6 Ma.

Besides magnitude (strength), scales of events are important in a solution of this task. Several examples, which involve Late Paleozoic and Quaternary megafloods, Hadean and Phanerozoic extraterrestrial impacts, and Phanerozoic mass extinctions, ensure that scaling by spatial extent and diversity of consequences facilitates tracing the boundary between catastrophes and “ordinary” events. This boundary, however, is dynamic and its position depends on our subjective needs. Considerations of the geologic past should not mix catastrophes of different scales. The event analysis helps to avoid such a pitfall, and, therefore, it should be preferred to neocatastrophism in modern geoscience.
