Underestimation of Planetary Contraction Due To Obscuration by Surface Roughness: The Case of Mercury

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Estimating Mercury's radial contraction is key to understanding the planet's geodynamic evolution. Contraction has been inferred from mapped shortening structures, whose heterogeneous distribution contradicts the isotropic contraction expected from global cooling.

A fully implicit second order method for viscous free surface Stokes flow – application to glacier simulations [PDF]

open access: yesGeoscientific Model Development
We present a fully implicit finite element method for viscous free surface Stokes problems which are common in glaciology and geodynamics. Standard fully implicit iterative solvers diverge for such problems when using large time steps. We address this by

Provenance of Middle Triassic sediments in the Southern Youjiang Basin: Insights from detrital zircon geochronology and tourmaline geochemistry

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
Middle Triassic turbidites in the Youjiang Basin were chiefly derived from a Late Palaeozoic continental arc along the southeastern South China Block, as revealed by detrital zircon U–Pb geochronology and tourmaline geochemistry, supporting a tectonic model driven by Paleo‐Pacific subduction rather than Paleo‐Tethyan closure.

Sedimentology and geochemistry of the recent sediments of the river system on Hurd Peninsula, Livingston Island, Antarctica

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
This study investigates the sedimentology and geochemistry of recent sediments from ephemeral river systems on Hurd Peninsula, Livingston Island, Antarctica. These systems are important for understanding sedimentary and geochemical processes in unique polar environments.

Plate movement and karstic underground water flow in fifty years of ultra broad band tilt observations in the Karst- implications for GNSS

open access: yes, 2016
The development of precision and length of available time series of continuous GNSS observations reveals an increasing multitude of observed crustal deformation signals.

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.
