Discrete breathers for understanding reconstructive mineral processes at low temperatures [PDF]

open access: yes, 2006
Reconstructive transformations in layered silicates need a high tem- perature in order to be observed. However, very recently, some systems have been found where transformation can be studied at temperatures 600 C below the lowest experimental results ...

Interstratified Illite‐Hydroxy‐Interlayered Smectite—A Disorder Structure Model for Quantification Using Rietveld Refinement

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 5, Page 801-812, October 2025.
ABSTRACT Background The acidic weathering of soils is known as a problem for decades. It leads to the deterioration of essential soil properties, including soil fertility, water, or cation buffering capacity due to solution and solid storage of Al3+ by polymerization in the interlayer of (former) swellable clay minerals.

Calibration, Validation and Evaluation of Machine Learning Thermobarometers in Metamorphic Petrology: An Application to Biotite and Outlook for Future Strategy

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 8, Page 755-780, October 2025.
ABSTRACT Geothermobarometry provides crucial constraints on the physical conditions of metamorphism, offering insights into petrogenetic processes and providing key information on thermal regimes and metamorphic depths to other geological disciplines.

Improvement of barrier properties of a hybrid sol-gel coating by incorporation of synthetic talc-like phyllosilicates for corrosion protection of a carbon steel [PDF]

open access: yes, 2012
Sol–gel coatings for corrosion protection of metals are a good alternative to toxic chromate treatments. The present work focussed on the incorporation of inorganic fillers in a sol–gel coating to improve the barrier properties of the film.

Low-grade metamorphism around the down-dip limit of seismogenic subduction zones: Example from an ancient accretionary complex in the Shimanto Belt, Japan [PDF]

open access: yes, 2011
International audienceReactions involving clay minerals during low-grade metamorphism at the depth of an ancient accretionary complex in the Shimanto Belt, Kyushu, Japan, were studied by integrated transmission electron microscopy-energy dispersive X-ray

Multiple Episodes of Fluid Alteration in Jezero Crater Indicated by MIST Mineral Identifications in PIXL XRF Data From the First 1100 Sols of the Mars 2020 Mission

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract The Mineral Identification by Stoichiometry (MIST) algorithm can identify mineral species in geochemical data sets. MIST is applied to X‐ray fluorescence chemical analyses from the Planetary Instrument for X‐ray Lithochemistry (PIXL) on the Mars 2020 Perseverance rover to identify mineral phases in abraded rock targets at Jezero crater.

Glen Torridon Mineralogy and the Sedimentary History of the Clay Mineral Bearing Unit [PDF]

open access: yes
Clay minerals are common in ancient terrains on Mars and their presence at the surface alludes to aqueous processes in the Noachian to Early Hesperian (>3.5 Ga). Gale crater was selected as Curiositys landing site largely because of the identification of
