Investigating the Antarctic Lithosphere Through Sp Receiver Function Analysis
To better understand the lithosphere of Antarctica, we imaged its lithosphere‐asthenosphere boundary (LAB) and crust‐mantle transition using Sp receiver functions from teleseismic events analyzed at individual stations and with common conversion point ...

Geodynamic conditions of rifting on the Earth surface: problems of studying
Rift structures are considered as elements of the composite structural parageneses of deformations in the crust and lithosphere with respect to kinematic types of such deformations.

Continental breakup and UHP rock exhumation in action: GPS results from the Woodlark Rift, Papua New Guinea [PDF]
We show results from a network of campaign Global Positioning System (GPS) sites in the Woodlark Rift, southeastern Papua New Guinea, in a transition from seafloor spreading to continental rifting. GPS velocities indicate anticlockwise rotation (at 2–2.7°

Sedimentation of the Lower Cretaceous Xiagou formation and Its Response to Regional Tectonics in the Qingxi Sag, Jiuquan Basin, NW China [PDF]
Under the constraint of an isochronous sequence stratigraphic framework, sediment infill of the Xiagou Formation reflects the overall control of dynamic tectonic movements and episodic sedimentations in the Qingxi Sag.

When do we need pan-global freeze to explain ^(18)O-depleted zircons and rocks? [PDF]
Rocks with δ^(18)O values of less than 5‰ SMOW (Standard Mean Ocean Water) contain oxygen derived from ∼0‰ seawater or meteoric (rain or melted snow,

Breakup Without Borders: How Continents Speed Up and Slow Down During Rifting
Relative plate motions during continental rifting result from the interplay of local with far‐field forces. Here we study the dynamics of rifting and breakup using large‐scale numerical simulations of mantle convection with self‐consistent evolution of ...

Large silicic magma reservoirs preferentially form in the upper crust of extensional continental environments. However, our quantitative understanding of the link between mantle magmatism, silicic reservoirs, and surface deformation during rifting is ...
