[1] The onset of subduction at passive margins has been extensively investigated and debated. However, the force constellations and mechanisms that enable the development of a subduction system from a passive margin remain unclear. This study presents new insights into the conditions and processes by which lateral density differences between oceanic and continental lithospheres in passive margins may lead to initiation of a low-angle subduction system. The presented study consists of (1… 
Subduction initiation at passive margins: Numerical modeling
[1] Subduction is a key process for terrestrial plate tectonics, but its initiation is still not entirely understood. In particular, despite the abundance of both passive and active continental
Numerical analysis of subduction initiation risk along the Atlantic American passive margins
As the oceanic lithosphere ages and cools, its density increases and at some stage exceeds the density of the underlying asthenosphere, so that the plate can sink spontaneously under its own weight.
Subduction initiates at straight passive margins
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
Kinematic Boundary Conditions Favouring Subduction Initiation at Passive Margins Over Subduction at Mid-oceanic Ridges
We perform numerical modelling to simulate the shortening of an oceanic basin and the adjacent continental margins in order to discuss the relationship between compressional stresses acting on the
Lateral propagation–induced subduction initiation at passive continental margins controlled by preexisting lithospheric weakness
TLDR
Three-dimensional numerical models are used to study the possibility of propagating convergent plate margins from preexisting intraoceanic subduction zones along passive margins [subduction propagation (SP)] and three possible regimes are achieved.

A tensile, flexural model for the initiation of subduction
We argue that subduction may be initiated at passive continental margins without shortening the lithosphere. Overcoming the lithosphere's high compressive strength requires special circumstances, and

Estimates of shear resistance associated with lithospheric thrusting and convergence represent lower bounds on the force necessary to promote trench formation. Three environments proposed as
Initiation of subduction at Atlantic-type margins: Insights from laboratory experiments
We have performed scaled lithospheric experiments to simulate the behavior of a ocean-continent plate system subjected to compressional strain over a geological timescale. Experiments have been

Although the initiation of subduction is a key element in plate tectonic schemes for evolution of lithospheric plates, the underlying mechanisms are not well understood. Plate rupture is an important
Detachment models for the formation of passive continental margins
The inherent asymmetry of extension by detachment leads to contrasting and conjugate classes of passive margins. Upper-plate margins comprise crust above a deeper detachment. Lower-plate margins

[1] Results of fluid dynamical experiments are presented to model the kinematics of lithospheric subduction in the upper mantle. The experiments model a dense high-viscosity plate (subducting
Analogue modelling of the initiation of subduction
SUMMARY We report the results of experiments on the initiation of subduction, using stratified analogue models in a large centrifuge, where the experiments are driven only by the enhanced gravity of

In the Australian continent, particularly in eastern Australia, the intraplate stresses and the absolute plate velocity trajectory are not aligned. This is in contrast to some lithospheric plates
