Model‐Based Interpretation of Solute Exports and Carbon Partitioning During Shale Weathering in a Mountainous Hillslope

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract The weathering of sedimentary rocks in high‐elevation catchments influences freshwater quality and the global carbon cycle. While individual biogeochemical mechanisms involved in this process are relatively well understood, quantifying their contributions to solute export and carbon fluxes under natural, transient conditions remains ...

Quantifying Multi‐Source Sediment Supply in a Tropical Foreland Basin (Oligocene‐Miocene Nyalau Formation, Borneo)

Basin Research, Volume 38, Issue 2, March/April 2026.
Detrital zircon unmixing identifies three sediment sources for the Oligocene–Miocene Nyalau Formation, including a previously unrecognised syn‐depositional component characterised by Oligocene–Miocene volcanic zircons and Neoproterozoic populations absent from established sources.

Overcoming Polyatomic Interferences in Sulfur Isotope Measurement Using MC‐ICP‐MS

Geostandards and Geoanalytical Research, Volume 50, Issue 1, Page 85-95, March 2026.
Key Points Optimising plasma conditions via the normalised argon index (NAI) reduces polyatomic interferences, allowing accurate sulfur isotope measurement in low‐resolution mode on MC‐ICP‐MS. Low‐resolution mode enhances sensitivity by approximately threefold compared with conventional high‐resolution analysis.

Comparing Groundwater Sampling Devices for Denitrification Assessment Using the N2/Ar Method

Groundwater, Volume 64, Issue 2, Page 235-242, March/April 2026.
Comparing N2, Ar, and excess‐N2 concentrations of groundwater samples collected with different devices shows that N2, Ar, and excess‐N2 concentrations significantly differ between the sampling devices. Using an electrical submersible pump for sampling yields the highest N2, Ar, and excess‐N2 concentrations.

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 405-426, March 2026.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...
