  1. #WeekendReading: Ouyang et al. on the Phanerozoic onset of large-scale continental #weathering. It does lean on K/Al, which I am having some issues with, but a good amount of other proxies show up as well.

  2. Aktuell versuche ich mich ja im #Altern bzw #Weathering von #Modelleisenbahn Fahrzeugen

    Hier eine Kleine Auswahl:
    Zwei Waggons in unterschiedlichen Bearbeitungsstufen

  3. Meine verhunzte Lok ist wieder schön 🥰


    Der Museumsbahnverein, der sie den ÖBB abkaufen möchte, und hat aber noch keinen Spender gefunden, der dieses Roststück wieder aufarbeiten lässt.

  4. Laterite (Pedology 🟤)

    Laterite is a soil type rich in iron and aluminum that often forms in hot, wet areas; most such soil is found in the tropics. Nearly all laterites are of rusty-red coloration due to high iron oxide content. Laterite soils develop by intensive and prolonged weathering of the underlying parent rock, usually under conditions of high temperatures and heavy rainfall...

  9. #Joy #Complexity #Richness #Rust #Paint #Corrosion #Decay #Beauty #Moss #Nature #Weathering

    As we countdown the last few days of the year, please take a moment to consider how beautiful, rich and detailed the world is.

    In a video game this fence might well be pristine, or maybe rust and moss would just be drawn on the surface but out in the world, each patch of green moss is fully 3D and, if only we looked, filled with tiny insect, and even tinier, microbial life.

    On the other side of the park is a similar railing, but it has the remains of three or four layers of different colour paint, peeling and bubbling, and little moss, but much more lichen.

    Every exposed surface in the city has some measure of similar complexity, and this is without even entering the park, or digging into the ground.

    Life is wonderful, and we, you and me, being here to see it is a miracle, and as a total non-believer I use that word deliberately, if carefully.

    May your 2026 be filled with childlike wonder.

  10. #Chitonida (#Mollusca) exist since the #Cambrian. Bodies are covered with #calcareous #plates, flexibly connected. Most feed on vegetation cover. The #CambrianExplosion made based i.a. on #oxygen significant leaps in #animalevolution. Y. Zhang et al. (2025) assume a change in Earth's orbit altering #solarradiation, leading to land #weathering and #nutrients flow to the sea. Algae thrived and produced much oxygen.

  11. And then one of the cats knocked the damn thing to the floor. Nose wheel broke and the repair looks like it was AI-generated 😅

    I applied a yellow-grey-buff dot filtering on the top, used some Industrial Earth on the bottom and satin varnished the thing. Too shiny, will do a matt one later. And after that I'll drybrush some black on the Vulcan port, maybe the vents too.

  12. Instead of a finely controlled and elegant pin wash I covered the whole F-15E model in a dynamic thinness wash of Abteilung's Sepia. After a bit of time I cleaned it mostly up. There's still more to do, and I'll use some dot filtering and/or buff later on some bits, and a bit of Industrial Earth on the underside. I think 😄

    The drop tank gluing sucks badly, and the left landing gear came off. This fiddliness aggravates me to no end.

  13. More tales from the , with this close up of the remains of the of a wild tree which had died, rotted and snapped at about 1m50 height. I don't know how the in the well of the formed, but presumably linked to the structure of the wood, and some kind of specific due to in the heat, and in the humidity.

    "HIGHLIGHTS:
    • [They] mapped channels and fossae within the volcanic plains east of Olympus Mons.
    • Late Amazonian channels east of Olympus Mons formed by eruptions of lava or water.
    • Fossae morphologies correspond to episodes of magmatic dike and sill emplacement.
    • Loading of Olympus Mons may control magmatic ascent processes and eruption types..."
