    Subsurface sediment remobilization and fluid flow in sedimentary basins: an overview

    , Basin Research, Vol: 22, Pages: 342-360

    Subsurface sediment remobilization and fluid flow processes and their products are increasingly being recognized as significant dynamic components of sedimentary basins. The geological structures formed by these processes have traditionally been grouped into mud volcano systems, fluid flow pipes and sandstone intrusion complexes. But the boundaries between these groups are not always distinct because there can be similarities in their geometries and the causal geological processes. For instance, the process model for both mud and sand remobilization and injection involves a source of fluid that can be separate from the source of sediment, and diapirism is now largely discarded as a deformation mechanism for both lithologies. Both mud and sand form dykes and sills in the subsurface and extrusive edifices when intersecting the sediment surface, although the relative proportions of intrusive and extrusive components are very different, with mud volcano systems being largely extrusive and sand injectite systems being mainly intrusive. Focused fluid flow pipes may transfer fluids over hundreds of metres of vertical section for millions of years and may develop into mud volcano feeder systems under conditions of sufficiently voluminous and rapid fluid ascent associated with deeper focus points and overpressured aquifers. Both mud and sand remobilization is facilitated by overpressure and generally will be activated by an external trigger such as an earthquake, although some mud volcano systems may be driven by the re-charge dynamics of their fluid source. Future research should aim to provide spatio-temporal 'injectite' stratigraphies to help constrain sediment remobilization processes in their basinal context and identify and study outcrop analogues of mud volcano feeders and pipes, which are virtually unknown at present. Further data-driven research would be significantly boosted by numerical and analogue process modelling to constrain the mechanics of deep subsurface s

    Simulating cardiac electrophysiology using anisotropic mesh adaptivity

    , Journal of Computational Science, Vol: 1, Pages: 82-88

    The simulation of cardiac electrophysiology requires small time steps and a fine mesh in order to resolve very sharp, but highly localized, wavefronts. The use of very high resolution meshes containing large numbers of nodes results in a high computational cost, both in terms of CPU hours and memory footprint. In this paper an anisotropic mesh adaptivity technique is implemented in the Chaste physiological simulation library in order to reduce the mesh resolution away from the depolarization front. Adapting the mesh results in a reduction in the number of degrees of freedom of the system to be solved by an order of magnitude during propagation and 2–3 orders of magnitude in the subsequent plateau phase. As a result, a computational speedup by a factor of between 5 and 12 has been obtained with no loss of accuracy, both in a slab-like geometry and for a realistic heart mesh with a spatial resolution of 0.125 mm.

    Tidal Modeling of an Ancient Tide-Dominated Seaway, Part 1: Model Validation and Application to Global Early Cretaceous (Aptian) Tides

    , Journal of Sedimentary Research, Vol: 80, Pages: 393-410, ISSN: 1527-1404

    <jats:title>Abstract</jats:title> <jats:p>The utility of deep-time global paleotidal modeling is evaluated with a series of modeling experiments focused on the Early Cretaceous (Aptian). The results from a series of paleobathymetry sensitivity experiments indicate that, despite paleogeographic and paleobathymetric uncertainty, appropriate use of global paleotidal models complements and enhances stratigraphic and sedimentological methods.</jats:p> <jats:p>Before being applied to global paleotidal modeling, the Imperial College Ocean Model (ICOM) is validated for the computation of modern global tides. The ICOM results only deviate slightly from a “state-of-the-art” published model and were achieved with considerably less computational expense and without data assimilation.</jats:p> <jats:p>The results from global paleotidal modeling of the Early Cretaceous (Aptian) were assessed by comparison with the published geological record. ICOM predicts high mesotidal to macrotidal ranges on the Arabian Platform, around India (especially to the north and west), along the Pacific coast between North and South America, northeast of Australia, and around Southeast Asia. The model predicts low microtidal ranges in the proto-South Atlantic Ocean and Weddell Sea.</jats:p> <jats:p>A further validation test assessed the ability of the model to predict the dominant tidal constituents (diurnal or semidiurnal) in the Aptian “Lower Greensand Seaway” of southeastern England and Northern France.

    Tidal Modeling of an Ancient Tide-Dominated Seaway, Part 2: The Aptian Lower Greensand Seaway of Northwest Europe

    , Journal of Sedimentary Research, Vol: 80, Pages: 411-439, ISSN: 1527-1404

    <jats:title>Abstract</jats:title> <jats:p>The Cretaceous Lower Greensand deposits of southeastern England and northern France contain abundant evidence of diurnal (once-daily) paleotides, with tidal influence increasing into the late Aptian. The Imperial College Ocean Model (ICOM) is used herein to determine the amplitude, origin (astronomical or co-oscillating), and characteristics (diurnal or semidiurnal) of the tides in the shallow marine “Lower Greensand Seaway” where these sediments were deposited.</jats:p> <jats:p>A global ocean paleotidal model of the Aptian predicts very low tidal ranges (microtidal) in the proto–Central Atlantic Ocean and Boreal Ocean, with higher tidal amplitudes, especially of the diurnal constituents, predicted in the northwestern Neotethys Ocean. This suggests that the Neotethys Ocean was the only significant source of oceanic tides to the Lower Greensand Seaway. Herein, the results of the global ocean paleotidal model are used to supply boundary conditions to a higher-resolution regional paleotidal model of the Lower Greensand Seaway. The regional paleotidal model shows that the tidal range of the Lower Greensand Seaway is largely controlled by the width of the connections to the open ocean. As sea levels rose during the Aptian, the oceanic connections widened, resulting in reduced frictional damping of the oceanic tidal wave. Coupled with funneling, shoaling, and Coriolis effects, this led to tidal amplification. Sensitivity tests using a variety of paleogeography and paleobathymetry scenarios suggest that the model predictions are robust.</jats:p> <jats:p>The global- to regional-scale paleotidal modeling presented here strongly suggests that there was a connection through France (in the Aube region of the Paris Basin) from the Neotethys Ocean to southeastern England. However, there are no time-equivalent deposits in this reg

    Normal fault growth and fault-related folding in a salt-influenced rift basin: South Viking Graben, offshore Norway

    , Journal of Structural Geology, Vol: 32, Pages: 490-506

    Three-dimensional seismic data were analysed to reconstruct the structural and stratigraphical development of a salt-influenced rift basin and thus gain an understanding of the relationships between normal fault growth, salt tectonics and the evolution of syn-rift depocentres. The Sleipner Basin, South Viking Graben, northern North Sea, is ca. 30 km long by 8 km wide and is bound to the east by a major extensional fault zone (Sleipner Fault Zone). Two types of fault-related fold are identified within the basin: (1) A fault-parallel monocline, interpreted as an extensional forced-fold, which formed through the upward propagation of the Sleipner Fault Zone through ductile evaporites of the Zechstein Supergroup and (2) three fault-perpendicular, salt-cored anticlines that compartmentalise the basin into four sub-basins and are related to displacement gradients along-strike of the Sleipner Fault Zone. Detailed seismic-stratigraphic analysis of pre- and syn-rift stratal units reveals a complex interplay between fault growth and salt movement which strongly controlled the evolution of syn-rift depocentres. During the early syn-rift, a series of depocentres, separated along-strike by the fault-perpendicular folds, were offset into the axis of the basin (ca. 3–4.5 km to the west of the Sleipner Fault Zone) by the fault-propagation fold. Later in the rift event, the influence of the fault-perpendicular folds depleted, resulting in a larger, interconnected depocentre that shifted into the immediate hangingwall of the fault as the surface of the fault-propagation fold was breached. The results of this study have implications for normal fault growth and sedimentary depocentre development in salt-influenced rift basins, and contribute to the general understanding of the controls on salt migration.
