  6. I just learned it was Texture Tuesday, so enjoy some (mostly) Brochantite (Cu₄SO₄₆) from a mine trip in a historic copper mine the other month.

  20. Added 25 mg/L Silicon (Si) and 5 mg/L Aluminium (Al) to the hydrogeochemical baseline of the Svystunova Gully mine water impoundment, modeling clay mineral phase equilibria using RedModRphree + PHREEQC (Thermoddem database, T = 12°C).

    Key thermodynamic outcome (pe–pH diagrams across pH 2–10):
    The solid-phase stability field is completely dominated by Beidellite(Na) and acidic forms of montmorillonite (Hmontmorillonite).

  25. Biogeochemical cycle (Biogeochemical cycle 🔄)

    A biogeochemical cycle, or more generally a cycle of matter, is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule...

  37. Du nouveau chez Minetosh online (minetoshsoft.com):

    Tous les modules d'« AmphiCalc-1 » destinés au calcul et à la classification des amphiboles ont été révisés. La saisie des valeurs pour déterminer la teneur en Fe₂O₃ et calculer les valences a été améliorée et simplifiée. Les calculs sont désormais effectués directement lors de la saisie. De plus, la valeur recherchée peut maintenant être déterminée plus rapidement à l'aide d'un curseur.

    Malheureusement, il y a des problèmes avec les navigateurs basés sur Chromium (par exemple Vivaldi). Firefox et ses dérivés fonctionnent. Désolé ! Je vais essayer de régler ce problème dès que possible.
