Wave-supported gravity flows (WSGFs) generate rates of sediment flux far exceeding other cross-shelf transport processes, contributing disproportionately to shelf morphology and net cross-shelf fluxes of sediment in many regions worldwide.

Interactions between tectonic, magmatic, sedimentary and hydrothermal processes during rifting and break-up of continental lithosphere lead to a variety of rifted margin types. As potential ...

Taking a global perspective, the book spans a range of timescales and content, ranging from how oceans transport particles, to how thick rock sequences are formed on continental margins. - Summarizes and integrates our understanding of …

Highest sedimentation rates and C org contents are found in hemipelagic sediments, because of high terrigenous sediment deposition and high biological productivity along continental margins. Authigenic sediments have the lowest rates of deposition and low C org % because the rate of precipitation of these oxides from seawater is so slow

The western continental margin of India (WCMI – Fig. 1), having a long sedimentation history since its origin, is considered to have undergone complex tectonic processes in the past ... To the east of this high, the margin hosts thick sedimentation demarcated with steep vertical down faulted sequences. The faulted sequences at the …

They also incorporate a more realistic style of post-rift sedimentation and margin progradation using a dynamically evolving depositional profile and present unprecedented detail for salt, syn- and post-rift stratigraphy that can be directly compared to natural examples from various salt-bearing continental margins.

Sediment accumulating on the continental margin builds up toward 'wave base', the depth to which, on a time-averaged basis, there is sufficient wave power to bypass sediment at a rate equal to its prevailing rate of input. ... In this paper, a theory of regime sedimentation is developed as a unifying idea for the analysis of continental ...

Continental margin, the submarine edge of the continental crust distinguished by relatively light and isostatically high-floating material in comparison with the …

Some platform environments are dominated by carbonate sedimentation while others are dominated by siliciclastic sedimentation. Figure (PageIndex{1}): USGS image depicting shields, platforms, basins, recent orogens (mountain belts), and other features. ... but also the Mediterranean Sea, and the Bay of Bengal. Nearly every continental margin ...

The link between Pleistocene glaciations and marine sedimentation has been explored in few studies (e.g., Maselli et al., 2011) that show that the dynamics of alpine glaciers modulate sediment input along continental margins, which ultimately interacts with eustasy in the formation of continental margin strata.

Western Norway is a classic example of a high elevation region bounding a rifted margin for which the tectonic evolution is debated 5,6,7,8,9.The study area is dominated by the Western Gneiss ...

Publication date: January 01, 1988. This synthesis covers stratigraphy, depositional processes, and geophysical interpretation of the major onshore and offshore marginal basins from Maine to the Bahamas, and includes an up-to-date review of thinking on regional tectonic history. Additional chapters discuss the theoretical aspects of thermal ...

Abstract. Sedimentation on continental margins bears the strong imprint of the tectonic setting, changes of sea-level and many local processes, including human intervention in …

This volume on continental margin sedimentation brings together an expert editorial and contributor team to create a state-of-the-art resource. Taking a global perspective, the …

Continental margins are also characterized by high sedimentation rates. Short-term mass transport of sediments is common, depending on the steepness of the slope. These episodic transport events occur at various intensities, ranging from slow-moving slope slides of intact layered packages to stirred-up, disorderly debris flows and …

The continental margin is a critical area connecting the deep-sea basin and the continent, and its sedimentation process is closely related to the input of terrestrial materials, seabed topography, inland climatic conditions, and marine environment. Therefore, sediments on the continental margin can effectively record the environmental evolution both in the …

The details of the sedimentation rates and year of deposition of the sediment at selected locations along the western continental margins have been discussed. During the SM-29 cruise, nearly three shallow water sediment cores (SWSC) were retrieved from the continental shelf of western India viz. Goa (GO), North …

The continental margins of East Antarctica and East Africa experienced massive rift related volcanism (Jacobs et al. 1996).This volcanism is thought to have been caused by lithospheric extension above a mantle plume (White and McKenzie 1989).The volcanism is well documented onshore in southeastern Africa, but less well so in East …

We are aware of the fact that contourites (sediments affected by alongslope bottom currents), turbidites (sediments deposited by downslope density currents) and pelagites (sediments deposited by vertical pelagic settling) simply represent extremes in a continuum of deep-sea sedimentary facies (Fig. 1).In fact, putting aside mass-transport …

Creation of Mountains due to Convergence ocean-continent (e.g., Andes, Cascades) continent-continent (e.g., Himalaya) begins as ocean-continent collision 1. rise of central igneous core "magmatic arc" • partial melting of oceanic crust + sediments + H2O* creates magmas of intermediate to felsic composition (i.e., continental crust) *H2O lowers the …

When rifting continental margins overlain by passive margins face each other, they are known collectively as "conjugate margins" as shown in the Black Sea example in Fig. 2. Fig. 2 ( a ) Schematic section of a rifted continental margin overlain by a wedge of passive margin sedimentation extending seaward and tapering onto oceanic …

Abstract. Sedimentation on continental margins bears the strong imprint of the tectonic setting, changes of sea-level and many local processes, including human intervention in sediment supply. Carbonate sediments are mainly created within the depositional basin whereas clastics supplied from upland areas are susceptible to enhancement due to ...

The morphology of divergent continental margins results from, amongst other things, rift processes, juxtaposition of oceanic, continental and transitional crust, and subsequent loading and shaping by sedimentary processes. Resulting morphologies have led to conventional classification of margin components into shelf, slope, rise and …
