  6. Interbedding (Petrology 💎)

    In geology, interbedding occurs when beds of a particular lithology lie between or alternate with beds of a different lithology. For example, sedimentary rocks may be interbedded if there were sea level variations in their sedimentary depositional environment. Intercalation is a special case of interbedding where a layer is variably inserted into an already existing s...

  8. I have an #ichnology question. In Tralee Ireland I came across calcareous flagstones with amazing serpitiform trace fossils. I've never seen anything quite so large with such a form. Individual traces are perhaps up to 50cm long by 2-3cm wide. Has anyone a name for this? The closest I can think of is taenidium serpentium but that shows meniscate backfills, not evident here.

    Answers greatfully received.

  13. After years of picking up #sand samples, I've finally gotten around to bottling them. IMHO they look fantastic; colours from white to black, yellow to orange and even green (olivene sand from the Isle of Skye) and purple (garnet sand from Easter Ross). My favourite is bimodal desert sand from Abu Dhabi, v well rounded grains associated with VF/F well sorted grains.

    Check out your local beach, esp the very back where interesting deposits often occur.

  18. The earliest known eukaryotic organisms were exclusively benthic, inhabiting shallow, oxygenated marine seafloors rather than drifting in the anoxic open oceans. Their evolution and geographic distribution were fundamentally constrained by the highly localized availability of oxygen.

  23. Just FYI, SedsOnline has a call for presenters on evaporites (and other chemical deposits). If you're studying the topic and would like to get a good exposure in the international sedimentological community, this is a good venue.

    “The Chiribiquete are table top mountains located deep in the Colombian Amazon and host many rare endemic species. Helanlin Xiang's work shows that the Chiribiquete Mountains likely upifted before the Early Miocene and could have acted as a long-lived stepping stone, connecting species in the Andes with the Guyana Shield…”

  43. 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...
