Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Recently, possible exceptionally young mare volcanic glass beads were discovered in Chang'e‐5 (CE‐5) samples. Isotopic dating suggests an age of approximately 120 Ma, presenting new challenges to existing lunar thermal evolution models. Thus, our research focuses on the source region of Rima Mairan, a branch of Rima Sharp, and its surrounding ...

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.

A Two‐Part Framework for Depth to Bedrock Prediction and Uncertainty Assessment in Sweden
European Journal of Soil Science, Volume 77, Issue 2, March–April 2026.ABSTRACT Accurate mapping of depth to bedrock (DTB) in complex post‐glacial landscapes is challenging due to high spatial variability and the prevalence of bedrock outcrops, which introduce “structural zeros” that violate standard regression modelling assumptions.

Pleistocene Smoothing and Resurfacing of Appalachian Ridgelines by Periglaciation
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Pleistocene cold periods created widespread periglacial conditions across mid‐latitudes, but isolating their geomorphic impact from modern climate, tectonics, and rock strength is challenging. We studied Appalachian (Eastern U.S.) ridgelines across a paleoclimate gradient, controlling for bedrock and structure, to test if colder periglacial ...

Erosional development of bedrock spur and gully topography in the Valles Marineris, Mars [PDF]
Gully networks separated by resistant bedrock spurs are a common erosional feature along the escarpments that border the Valles Marineris. The resistant spur topography is best developed where the base of the slope is truncated by linear scarps ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Soil production, through bedrock weathering, regulates landscape evolution, biogeochemical cycles, and societal sustainability, yet quantifying soil production rates (SPRs) remains difficult due to limited tools. Here, we present a new framework for measuring SPRs based on uranium comminution ages and validate this approach at a deep granitic ...

Aspects of the geomorphology of the Greywacke Ranges bordering the Lower and Middle Waikato Basins [PDF]
, 1967 The fault-bounded blocks which make up the Greywacke Ranges bordering the Lower and Middle Waikato Basins have a deep red-weathered regolith and are covered by mantles of volcanic ash which can be used for dating ground surfaces.
