Trace Element Transport and Deposition During Magmatic Degassing: The Effect on Martian Rocks and Fines

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Martian magmas compositionally resemble those from terrestrial continental hotspot magmatic suites, characterized by low OH and high Cl and S contents. The magmatic gases exsolved from such magmas transport a variety of metal complexes and, upon cooling, precipitate vapor‐deposits into vugs and fractures within rocks and on the surfaces of ...

Magnetic Properties of Martian Impact Basins Including the Effect of Mantle Excavation

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The weak magnetism of many impact basins on Mars has historically been interpreted as evidence of the martian dynamo's cessation before ∼4.0 Ga. However, expected magnetic properties of these impact basins are poorly known because basin formation exhumes and recrystallizes mantle material, which has not been sampled by martian meteorites ...

Tracing Fluid‐Rock Interactions and Migration Pathways in Shallow Megathrust Shear Zones Through Rock Magnetic Analysis

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Megathrust shear zones are the main fluid transport pathways during the seismic cycle and play a key role in controlling physicochemical alteration. Defining fluid‐rock interaction in wall rocks provides evidence for unraveling the hydrogeology of shear zones and their link to active fluid circulation.

Magnetic Mineralogy in Lunar Mare Basalts and Implications for Paleointensity Retrieval

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Lunar paleomagnetic studies have identified multidomain metallic Fe–Ni alloys as the dominant magnetic contributors in mare basalts. Here, we explore the low‐temperature magnetic behavior of standard samples for a suite of opaque minerals that occur within mare basalts (single‐domain and multidomain Fe, wüstite, ulvöspinel, iron chromite ...

Efficiency of Thermoremanent Magnetization Acquisition in Vortex‐State Particle Assemblies

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Magmatic rocks record ambient magnetic fields during cooling, preserving them for billions of years through thermoremanent magnetization (TRM). TRM accuracy depends on particle size, shape, magnetic properties, and the number of particles available to record the field.

Exploring the origins of magnetization within the Chicxulub crater upper peak ring

Meteoritics &Planetary Science, Volume 60, Issue 4, Page 823-848, April 2025.
Abstract Large terrestrial impacts may produce vast subsurface hydrothermal systems, capable of generating conditions favorable to the origin of life. Modeling suggests that these systems may persist for >1 million years for basin‐sized craters; however, direct experimental constraints on hydrothermal system duration are needed.
