Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Aluminum phyllosilicates occur in 1–10s of km2 exposures of Noachian (∼3.7 Ga) rock across Mars and typically appear stratigraphically above Fe/Mg‐phyllosilicates. These units have been proposed to represent pedogenic basalt weathering sequences.

Alteration of Feldspar‐Rich Rocks on Ancient Mars and Its Possible Link to Ca/Fe‐Rich Carbonates
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Feldspar‐rich rocks have increasingly been discovered on the martian surface. They may have been an important part of the ancient martian crust and may be related to Ca/Fe‐rich carbonates (one of two types of carbonates on Mars and the other being Mg‐rich carbonates), but compared to mafic rocks, their interaction with water on ancient Mars is

Oxychlorine Species on Mars: A Review
Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Water Resources Research, Volume 61, Issue 12, December 2025.Abstract Groundwater dating studies rely on environmental tracers to estimate residence times, but most available reliable tracers cover either short (days to decades; e.g., 222Rn, 3H/3He, 85Kr) or extended timescales (millennia to millions of years; e.g., 4He, 36Cl, 81Kr). This leaves a critical gap in age information for intermediate residence times (

An Analytical Model for Evaluating the Hydraulic Conductivity of the Fracture‐Conduit‐Matrix System
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract In the fracture‐conduit‐matrix system, distinct shape differences among water‐conducting channels (fractures and conduits) hinder developing an analytical model for flow characteristics and hydraulic conductivity assessment. To address this, we introduce the elliptic‐conduit‐matrix model (ECMM) under velocity slip interface conditions.

Transient Hydrology in Amazonis Planitia (Mars) in the Aftermath of the Tooting Impact
Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.Abstract Hydrological flows generated by meteoroid impact are still largely unexplored on Mars and may also have implications for Earth. We reconstructed the hydrological sequence initiated on Mars by a less than 3 Ma old meteoroid impact that formed the 28 km‐wide Tooting crater on Amazonis Planitia, an ice‐bearing region.

Transactions in GIS, Volume 29, Issue 7, November 2025.ABSTRACT The Southern Resident killer whales (SRKW) are an endangered species that occupy marine environments on the west coast of North America, including the Salish Sea. Representing marine species in this environment can be achieved by multidimensional space–time simulation modeling that provides more information about locations and behaviors for ...
