7 de feb. de 2023 · 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 ...
1 de ago. de 2023 · In this manuscript, we summarise the evolution and key features of each tectonic model before discussing their shortcomings; particularly in light of recent studies (e.g. Advokaat et al., 2018, Lin et al., 2020).We present flaws in all the currently debated models and propose an alternative kinematic model for South China Sea rifting favouring the development of long-lived back arc extension ...
Continental Rifting Figure \(\PageIndex{1}\): Faulting that occurs in divergent boundaries. In places where the continental plates are very thick, they reflect so much heat back into the mantle it develops strong convection currents that push super-heated mantle material up against the overlying plate, softening it.
24 de abr. de 2015 · 1 Introduction. Continental rifting results from extensional deformation of the continental lithosphere leading to its rupture and potentially subsequent formation of a new oceanic domain [Şengör and Burke, 1978; Khain, 1992; Ziegler, 1992a].Rifting plays consequently a major role in the evolution of the continental lithosphere and, in particular, in the so-called Wilson cycle describing the ...
1 de oct. de 2015 · Heterogeneities in the continental lithosphere may influence rifting processes. The presence of preexisting thin lithosphere can enhance melt generation and ponding during extension (Armitage et al., 2010). Variations in lithospheric thickness can also promote lateral melt migration to regions of thinner lithosphere (Ebinger and Sleep, 1998).
A consensus has thus been reached that rifting is fundamentally multiphase and results from the interaction of crustal and mantle processes. A significant knowledge evolution has not only occurred in our way of describing the strain evolution of rifted margins, but also in our understanding of the way that deformation is coupled with magmatic, thermal, and isostatic processes.
28 de may. de 2022 · It provides the definition of the active and passive rifting categories, as these are regularly mentioned in the literature and are the primary designations of extensional rift settings. The chapter lists the major tectonic structures and basin types encountered in rifts and rifted margins.
