Nanoscale Infrared Imaging Analysis of Carbonaceous Chondrites to Understand Organic-Mineral Interactions During Aqueous Alteration [PDF]

, 2019
Organic matter in carbonaceous chondrites is distributed in fine-grained matrix. To understand pre- and postaccretion history of organic matter and its association with surrounding minerals, microscopic techniques are mandatory.

Clay Reimagined: Phyllosilicates as Future Membrane Technologies

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Recent advancements in membrane technologies based on 2D materials have drawn attention for molecular‐scale separations owing to these materials’ tunable nanoscale interlayer properties. Phyllosilicates, natural and abundant layered clay minerals, have emerged as scalable and cost‐effective candidates.

How phyllosilicate mineral structure affects fault strength in Mg-rich fault systems [PDF]

, 2017
The clay mineralogy of fault gouges has important implications for the frictional properties of faults, often identified as a major factor contributing to profound fault weakness.

Adsorption of Protamine and Papain Proteins on Saponite

Clays and Clay Minerals, 2008
AbstractDue to the increased importance of bionanocomposites, protamine and papain proteins were adsorbed on Na+- and on Cs+-exchanged saponite from aqueous solution. Protein analysis of equilibrium solutions and thermogravimetric analyses of biocomposites were used to prepare adsorption isotherms.

Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.

Tracing a Wet Past and Diverse Provenances in Gale Crater, Mars, With Lithium Content Using ChemCam on the Curiosity Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The incompatible behavior of Lithium during magmatic differentiation and high mobility during aqueous alteration make it a valuable tracer of crustal processes on Mars. Its preferential incorporation into secondary phyllosilicates further links Li to clay‐forming environments, which are critical for evaluating past aqueous activity and ...

Rapid terrestrial weathering of the CI1 carbonaceous chondrite find Oued Chebeika 002

Meteoritics &Planetary Science, Volume 61, Issue 2, Page 211-223, February 2026.
Abstract Alteration of historic CI1 meteorite falls during their curation demonstrates the susceptibility of smectite‐rich carbonaceous chondrites to terrestrial exposure. The discovery of Oued Chebeika 002 in Morocco in June 2024 presents a unique opportunity to document the earliest stages of weathering of a CI1 find.

Amazonian Hydrothermal Alteration Comparing Nakhlite Secondary Mineralogy to Water Rock Reaction Experiments [PDF]

, 2018
We report on results from experiments with Mars analog materials under diagenetic conditions. The mineralogical results of our experiments suggest that an important type of fluid alteration in the Amazonian may be short duration (e.g.
