Mantle Transition Zone Topography in New Zealand From Teleseismic P $P$‐Wave Receiver Functions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The geology of New Zealand has been shaped by tectonic plate interactions driven by mantle convection over the past 60 million years, but the effects of these interactions on the transition to the lower mantle are not yet well understood. We analyze 10 years of teleseismic P $P$‐wave receiver functions using common conversion point stacking to

Numerical Modeling of Purely Active (Plume‐Produced) Continental Rifting and Break‐Up

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract In contrast to the traditional mechanism of passive continental rifting (driven by far‐field tectonic forces), the active rifting‐to‐break‐up processes (caused by rising mantle plumes) are still poorly understood. However, most episodes of fragmentation of the last supercontinent Pangea were relatively shortly preceded (within ∼10 Myr) by the ...

Large‐Scale Flow Toward Low‐Velocity Anomalies Reconciles Seismic and Geodynamic Constraints in the Deepest Mantle Beneath Alaska

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Deep mantle downwellings are typically located away from the two Large Low‐Velocity Provinces (LLVPs) in Earth's mantle. Geodynamic models based on global seismic tomography generally predict that convective flow at the core‐mantle boundary spreads laterally away from downwelling regions and toward LLVPs.

Origin of the Bulge Topography Within Caloris Basin, Mercury

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Caloris basin on Mercury has a massive circular bulge topography imprinted with unique fault sets. A variety of deformational processes have been proposed to have influenced their formation, including both global contraction and basin evolution, as well as the deposition and weight of the volcanic infill.

Evolution and Provenance of the Polish Rotliegend in the Southern Permian Basin

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The Southern Permian Basin (SPB) has been extensively explored for ore deposits. However, a comprehensive evaluation of the remaining copper potential, specifically for sediment‐hosted stratiform copper system, remains lacking. This study applies goSPL, an open‐source landscape and stratigraphic evolution model, to reconstruct the Permian rift‐

Subglacial Topography of Coats Land Records Post‐Gondwanan Landscape Evolution and Early Ice‐Sheet Behavior in East Antarctica

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The East Antarctic Ice Sheet (EAIS) formed circa 34 million years ago and now contains an ice volume equivalent to ∼52 m of global sea‐level rise. Although the EAIS is approximately in balance today, there is substantial uncertainty regarding the sensitivity of sectors underlain by low‐lying bed topography to future climate and ocean warming ...

A Lithospheric Drip Triggered Green and Colorado River Integration

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The integration of the Green and Colorado Rivers shifted the continental drainage divide of North America, marking a key event in the hydrological and biogeographical evolution of the continent. Sedimentological and stratigraphic evidence shows that for integration to occur, the Green River likely cut through the Uinta Mountains between 8 and ...
