Introduction: The crustal dichotomy and the Tharsis volcanic province are dominant features at Martian surface. Both exogenic (giant impact) and endogenic (e.g., degree-1 convection) were proposed to explain the dichotomy. In a recent study Zhong [1] proposed a unified model for the Tharsis rise and the dichotomy. A lithospheric thickness variations of hemispherical pattern is assumed, consiste...

The long-term stress-state of the lithosphere results from a combination of boundary forces, surface loads and tractions frommantle flow. Here, we have employed a numerical technique which allows for the selfconsistent treatment of the interaction between the lithosphere and mantle and takes into account the deformation of the free-surface. We have used this to study lithospheric dynamics in or...

[1] Using traveltimes of teleseismic body waves recorded by several temporary local seismic arrays, we carried out finite‐frequency tomographic inversions to image the three‐ dimensional velocity structure beneath southern Tibet to examine the roles of the upper mantle in the formation of the Tibetan Plateau. The results reveal a region of relatively highP and S wave velocity anomalies extendin...

[1] Crustal deformation along the present-day northern margin of the Tibetan Plateau has occurred since mid to late Eocene time, soon after India collided with Eurasia. Assuming that on these distance and time scales the lithosphere can be approximated using a thin viscous sheet, we show that far-field lithospheric deformation caused by an indenting boundary is expected to start shortly after c...

In this paper, methods to separate the ionospheric and the scattering contributions on SAR data are proposed, and the dynamic components of the ionosphere and the lithosphere are quantitatively retrieved. These methods exploit changes of squint and time in the azimuth subbands.

The sinking of lithosphere at subduction zones couples Earth’s exterior with its interior, spawns continental crust and powers a tectonic regime that is unique to our planet. In spite of its importance, it is unclear how subduction is initiated. Two general mechanisms are recognized: induced and spontaneous nucleation of subduction zones. Induced nucleation (INSZ) responds to continuing plate c...
