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
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 and fluidization of
unconsolidated ...
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
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 faulting, coeval with differential
upli...
Liquid–solid suspension theory with reference to possible applications in geology
Basin Research - Tập 22 Số 4 - Trang 591-602 - 2010
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 system from a fluid dynamic
point of ...
Fluvial response to sea‐level changes: a quantitative analogue, experimental approach
Basin Research - Tập 13 Số 3 - Trang 269-292 - 2001
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 stratigraphy to
the sea‐level cu...
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
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 by isolating governing
paramete...
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
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 accretionary types of shelf‐break are distinguished based o...
The effective elastic thickness of the lithosphere and the evolution of foreland basins
Basin Research - Tập 4 Số 3-4 - Trang 169-178 - 1992
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 the involvement of
factors other...
Fluid dynamics and subsurface sediment mobilization processes: an overview from Southeast Caribbean
Basin Research - Tập 22 Số 4 - Trang 361-379 - 2010
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 sediment
mobilization features in...
Subsurface sediment remobilization and fluid flow in sedimentary basins: an overview
Basin Research - Tập 22 Số 4 - Trang 342-360 - 2010
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 these groups are not
always disti...
3D numerical modelling of marine organic matter distribution: example of the early Jurassic sequences of the Lusitanian Basin (Portugal)
Basin Research - Tập 30 Số S1 - Trang 101-123 - 2018
AbstractDue to the multiple controlling factors involved, it is a challenging
task to identify and quantify the processes influencing the distribution and
heterogeneity of marine organic‐rich rocks. To improve our understanding of
these deposits, we model their burial history and stratigraphic evolution as
well as processes linked to marine organic matter history throughout the Lower
Jurassic in o...
