Passive Continental Margins and Abyssal Plains

2010
Nearly the entire Atlantic Ocean and large portions of the Indian Ocean are surrounded by passive continental margins (Fig. 4.1). In contrast, the Pacific Ocean is mostly bordered by active continental margins. As mentioned in Chapter 1, passive continental margins are not plate boundaries because the continental plate is firmly attached to the ...

Mantle exhumation at passive margins

Earth and Planetary Science Letters, 1996
Abstract Laboratory models of lithosphere necking have been used to study the modes of passive margin formation and related mantle exhumation at continent-ocean boundary. Four-layer models were constructed with sand and silicone putty, to represent the brittle and ductile layers, respectively, of both crust and mantle. It is shown that necking of the

Subduction initiates at straight passive margins

Geology, 2014
Subduction initiation at straight passive margins can be investigated with two-dimensional (2-D) numerical models, because the geometry is purely cylindrical. However, on Earth, straight margins rarely occur. The construction of 3-D models is therefore critical in the modeling of spontaneous subduction initiation at realistic, curved passive margins ...

Passive margins and their subsidence

Journal of the Geological Society, 1992
Three main types of subsidence dominate the vertical tectonics of rifted inter-plume passive margins. These are the isostatic response to (1) stretching and thinning of the crust and lithosphere (syn-rift stage), (2) cooling and thickening of the lithosphere (mainly post-rift stage), and (3) sediment loading (both stages).

Passive continental margins: A review

Reviews of Geophysics, 1983
This appears to be the first U.S. I.U.G.G. quadrennial report on passive continental margins. For this reason alone a systematic review of all of the noteworthy literature would be voluminous. In addition very significant advances have been made during the past several years toward understanding the major stages of evolution of these margins. For these

Passive margins: A model of formation

Journal of Geophysical Research: Solid Earth, 1981
The stretching model of McKenzie is applied to the formation of passive continental margins, assuming local isostatic equilibrium. We present the quantitative implications of the model; we then discuss its fit to the IPOD data on the Armorican and Galicia continental margins of the northeast Atlantic.

Rifts and Passive Margins

2015
Rifts and passive margins are extremely important for the petroleum industry, as they are areas of high sedimentation and can contain significant oil and gas resources. This book provides a comprehensive understanding of rifts and passive margins as a whole.

Focused fluid flow in passive continental margins

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005
Passive continental margins such as the Atlantic seaboard of Europe are important for society as they contain large energy resources, and they sustain ecosystems that are the basis for the commercial fish stock. The margin sediments are very dynamic environments.

Passive margin clinothems revisited – TheNew Jersey margin example

2016
Passive margin are for a long time used to reconstruct globalsea-level variations at geological time scale for various reasons.They usually show a simple and undeform sedimentary record witha possibility to correlate unconformities regionally and in somecases worldwide, a gradational evolution of depositional environmentsfrom the continental to the ...
