Diverse products of near‐surface sediment mobilization in an ancient eolianite: outcrop features of the early Jurassic Navajo Sandstone
Basin Research - Tập 22 Số 4 - Trang 578-590 - 2010
Gerald Bryant, Andrew D. Miall
ABSTRACTThe Navajo Sandstone of the Colorado Plateau, USA, displays a wide range of soft‐sediment deformation (SSD) features, including decametre‐scale features that have not been found in any modern desert environment. Laboratory simulations and partial analogues from other depositional environments suggest that these features derived from episodic liquefaction an...... hiện toàn bộ
Normal faulting, extension and uplift in the outer thrust belt of the central Apennines (Italy): role of the Caramanico fault
Basin Research - Tập 14 Số 2 - Trang 225-236 - 2002
F. Ghisetti, Livio Vezzani
AbstractThe outer Adriatic zones of the central Apennines (Italy) provide good conditions for analysing geometry and kinematics of the earliest normal faults, superposed onto the thrust belt. During the latest stages of thrusting onto the Adriatic foreland (late Pliocene–early Pleistocene), the outermost imbricates of the thrust belt were subjected to normal faulti...... hiện toàn bộ
Liquid–solid suspension theory with reference to possible applications in geology
Basin Research - Tập 22 Số 4 - Trang 591-602 - 2010
Renzo Di Felice
ABSTRACTThe first part of this paper provides an overview of the state of the art of the hydrodynamics of liquid suspensions of solid particles. It is shown that knowledge of the suspension Archimedes number is sufficient to estimate the voidage–velocity parameters for suspensions of solids possessing homogenous characteristics, thereby completely defining the syst...... hiện toàn bộ
Fluvial response to sea‐level changes: a quantitative analogue, experimental approach
Basin Research - Tập 13 Số 3 - Trang 269-292 - 2001
M. W. I. M. Van Heijst, George Postma
ABSTRACT Quantitative evaluation of fluvial response to allogenic controls is crucial for further progress in understanding the stratigraphic record in terms of processes that control landscape evolution. For instance, without quantitative insight into time lags that are known to exist between sea‐level change and fluvial response, there is no way to relate fluvial s...... hiện toàn bộ
Quantitative analogue flume‐model study of river–shelf systems: principles and verification exemplified by the Late Quaternary Colorado river–delta evolution
Basin Research - Tập 13 Số 3 - Trang 243-268 - 2001
M. W. I. M. Van Heijst, George Postma, Xander D. Meijer, Jennifer Nicolette Snow, John B. Anderson
ABSTRACT Physical modelling of clastic sedimentary systems over geological time spans has to resort to analogue modelling since full scaling cannot be achieved within the spatial and temporal restrictions that are imposed by a laboratory set‐up. Such analogue models are suitable for systematic investigation of a sedimentary system's sensitivity to allocyclic changes ...... hiện toàn bộ
Influence of point‐source sediment‐supply on modern shelf‐slope morphology: implications for interpretation of ancient shelf margins
Basin Research - Tập 21 Số 5 - Trang 484-501 - 2009
Cornel Olariu, Ronald J. Steel
ABSTRACTPresent sea‐floor bathymetry indicates that the continental‐shelf and shelf‐break morphology have some unique and predictable characteristics in areas with and without high sediment supply. Using a global bathymetry dataset in open shelf areas in front of rivers that discharge over 25 × 106 tons of sediment per year, five distinct accre...... hiện toàn bộ
The effective elastic thickness of the lithosphere and the evolution of foreland basins
Basin Research - Tập 4 Số 3-4 - Trang 169-178 - 1992
A. B. Watts
AbstractThe elastic thickness of the continental lithosphere is strongly ‘bi‐modal’. Foreland basins reflect this bi‐modality with narrow, deep basins (e.g. Apennines) and wide, shallow ones (e.g. Ganges). The bi‐modal distribution cannot be explained by thermal models which describe the relationship between elastic thickness and plate age in the oceans, suggesting...... hiện toàn bộ
3D seismic interpretation of slump complexes: examples from the continental margin of Israel
Basin Research - Tập 17 Số 1 - Trang 83-108 - 2005
Jose Frey Martinez, Joe Cartwright, Ben Hall
AbstractThis paper uses three‐dimensional (3D) seismic data from the continental margin of Israel (Eastern Mediterranean) to describe a series of slump deposits within the Pliocene and Holocene succession. These slumps are linked to the dynamics of subsidence and deformation of the transform margin of the eastern Mediterranean. Repeated slope failure occurred durin...... hiện toàn bộ
Fluid dynamics and subsurface sediment mobilization processes: an overview from Southeast Caribbean
Basin Research - Tập 22 Số 4 - Trang 361-379 - 2010
Éric Deville, Sophie‐Hélène Guerlais, Siegfried Lallemant, F. Schneider
ABSTRACTThis paper discusses the origin and the dynamics of subsurface sediment mobilization processes in tectonically mobile regions and shale‐rich environment. This is illustrated by the example of Trinidad and the south of the Barbados prism. In this area of the southeast Caribbean, geophysical acquisitions have spectacularly shown the widespread development of ...... hiện toàn bộ
Subsurface sediment remobilization and fluid flow in sedimentary basins: an overview
Basin Research - Tập 22 Số 4 - Trang 342-360 - 2010
Mads Huuse, Christopher Jackson, Pieter Van Rensbergen, Richard J. Davies, Peter B. Flemings, Richard J. Dixon
ABSTRACTSubsurface 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 ...... hiện toàn bộ
