  1. Corundum (structure) (Mineralogy 💎)

    Corundum is the name for a structure prototype in inorganic solids, derived from the namesake polymorph of aluminum oxide. Other compounds, especially among the inorganic solids, exist in corundum structure, either in ambient or other conditions. Corundum structures are associated with metal-insulator transition, ferroelectricity, polar magnet...

  2. Fluid inclusion (Mineralogy 💎)

    A fluid inclusion is a bubble of fluid that is trapped within a crystal. As minerals often form from a liquid or aqueous medium, tiny bubbles of that liquid can become trapped within the crystal, or along healed crystal fractures. These inclusions usually range in size from 0.01 mm to 1 mm and are only visible in detail by microscopic study, however specimens of...

  3. Geode (Petrology 💎)

    A geode 'earthlike') is a geological secondary formation within sedimentary and volcanic rocks. Geodes are hollow, vaguely spherical rocks, in which masses of mineral matter are secluded. The crystals are formed by the filling of vesicles in volcanic and subvolcanic rocks by minerals deposited from hydrothermal fluids; or by the dissolution of syngenetic concretions and partial filling by the same...

  5. One for the Python-minded spectral geologists, particularly those down under (..if any exist on the fediverse).

    I've been putting a bit of work into tsg-xr to make HyLogger hyperspectral scanning data a bit more accessible via Python - and more specifically interoperable via xarray.

    A bit of an overview here: fluids.rocks/posts/tsgxr/

  18. Striation (geology) (Mineralogy 💎)

    In geology, a striation is a groove, created by a geological process, on the surface of a rock or a mineral. In structural geology, striations are linear furrows, or linear marks, generated from fault movement. The striation's direction reveals the movement direction in the fault plane. Similar striations, called glacial striations, can oc...

  33. Hiroshimaite is an exotic product of the historic Hiroshima nuclear explosion at the end of World War Two. It is similar in nature to trinitite from the Trinity explosion during the Manhattan Project. Hiroshimaite is much more rare than trinitite.

  36. Lithophysa (Mineralogy 💎)

    A lithophysa is a felsic volcanic rock with a spherulitic structure and interior cavity with concentric chambers. Its outer shape is spherical or lenticular. They vary in size from very small up to twelve feet in diameter depending on the age of the magma chamber. These rocks are usually found within obsidian or rhyolite lava flows. Lavas low in feldspar ...

  41. 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.
