    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.

    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.

    Timing and extent of late Quaternary glaciation in the western Himalaya constrained by <sup>10</sup>Be moraine dating in Garhwal, India

    , Quaternary Science Reviews, Vol: 29, Pages: 815-831, ISSN: 0277-3791

    Glacial chronologies from the Himalayan region indicate various degrees of asynchronous glacial behavior. Part of this has been related to different sensitivities of glaciers situated in contrasting climatic compartments of the orogen, but so far field data in support for this hypothesis is lacking. Here, we present a new 10Be-derived glacial chronology for the upper Tons valley in western Garhwal, India, and initial results for the Pin and Thangi valleys in eastern Himachal Pradesh. These areas cover a steep gradient in orographic precipitation and allow testing for different climatic sensitivities. Our data provide a record of five glacial episodes at ∼16 ka, ∼11-12 ka, ∼8-9 ka, ∼5 ka, and <1 ka. In the Thangi valley, our results indicate a glacial episode at ∼19 ka, but no data are available for younger glacial deposits in this valley. At their largest mapped extent (∼16 ka), the two main glaciers in the upper Tons valley joined and descended down to ∼2500 m asl, which represents a drop of ∼1400 m compared to the present-day glacial extent. During the Holocene the two largest glaciers produced distinct glacial landforms that allowed us to reconstruct changes in the Equilibrium Line Altitude (ELA) over ∼20 km north-south distance that is presently associated with a steep gradient in rainfall. We observe that ELA-changes have been consistently ∼2 times higher for the glacier located in a presently wetter climate, pointing at different climate sensitivities, related to the amount of precipitation that they receive. At regional scale, our data is in reasonable agreement with other published glacial chronologies from the western Himalaya and suggest that glacial advances during the Holocene have been largely synchronous in this region. Comparison of glacial chronologies from the western Himalaya with other palaeoclimatic proxy data suggests that long-term changes in glaci
