Mineral Reaction Kinetics During Water–Rock Interactions of Julong Hot Springs, Northern China

open access: yesGeofluids
To elucidate the water–rock interaction mechanisms of the Julong Hot Springs in Changbai Mountain, this study first analyzed the leaching patterns of hydrochemical components in water–rock interactions. The PHREEQC software was then utilized to calculate

Porous and Permeable Crystalline Basement: Evidence for Large‐Scale Hydraulic Connectivity at Kivetty, Finland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

open access: yesGeophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

Pressure induced elastic softening in framework aluminosilicate-albite (NaAlSi3O8)

open access: yes, 2016
Albite (NaAlSi3O8) is an aluminosilicate mineral. Its crystal structure consists of 3-D framework of Al and Si tetrahedral units. We have used Density Functional Theory to investigate the high-pressure behavior of the crystal structure and how it affects

Fossils as cultural heritage: Scientific, commercial and legislative issues

open access: yesGeology Today, Volume 42, Issue 5, Page 263-272, September/October 2026.
Fossils are among the principal sources for understanding the history of life through ‘Deep Time’ and can inform projections of biotic responses to environmental change. Despite a widespread recognition of the scientific, historical and communication significance of fossils in our culture, their role as part of our cultural heritage is still far from ...

Le chloritoïde dans les paragenèses à glaucophane, albite ou paragonite

open access: yes, 1972
The stability fields of chloritoid plus sodic silicate assemblages have been placed in pressure-temperature coordinates as a function of possible reactions among the phases albite, paragonite, chloritoid, chlorite and glaucophane. The construction of the

An Exploration of Mechanochemical Activation on Various Potential Supplementary Cementitious Materials

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT The use of supplementary cementitious materials (SCMs) is a major way to reduce the carbon footprint of concrete. Mechanochemical activation (MCA) can be used to activate inert materials that can then be used as SCMs. In this study, the effect of MCA using a planetary ball mill was investigated for 16 materials, ranging from natural occurring ...
