The #Seds_Online Team invites to the April Webinar titled 'Rapid growth and recrystallization of cave pearls: implications for carbonate diagenesis' from Leslie A. Melim, today at 4 pm UK: sedsonline.com/future-webin...

Day 3 of the @DerbyUni #GeoEnergy field trip is #CriticalMinerals day! Today we are looking at how the #EnergyTransition to #Carbon #NetZero will require significant investment in #Geoscientists.

Starting in 15 minutes!👇🏽

Day 2 of our @DerbyUni #GeoEnergy field trip finds us in Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿! Today we are looking at the #energy production and storage potential of rocks deposited in deltas, deserts and shallow tropical seas. #CCS #geothermal

Let’s kick off our 1st #SabkhaSaturday with some microbial mats in Abu Dhabi. Microbial mats can develop with a range of morphologies. This polygonal growth pattern, with uplifted margins, is typical of rapid healthy growth in the uppermost intertidal zone. Explained here: dx.doi.org/10.1002/dep2...

For today’s #SabkhaSaturday offering, we present… 🥁 …. an intertidal creek in the Abu Dhabi Sabkha. These meandering channels are the focal points of flow during the later stages of ebb tides. Thus, transporting significant amounts of sediment seawards.

In the February @sedsonline.bsky.social Webinar, Liz Mahon from the University of Utah will talk about coastal peatland systems. The Webinar is held today at 5 pm CET: sedsonline.com/future-webin... #Seds_Online

Really looking forward to this!👇⚒️

The Seds Online February Webinar is TODAY! 'Exploring coastal peatland systems: case studies from the Late Cretaceous and Paleocene' with the amazing Liz Mahon. sedsonline.com/future-webin... Today at 5 pm CET! ⚒️ 🧪

Back on the surface of the sabkha this #SabkhaSaturday. The pustular surface seen in this image is caused by the displacive growth of a halite cement between the bioclastic sand grains. This ephemeral cement will be dissolved by rain fall, storm surges or, even, humidity.

Desiccation polygons in thin microbial mats. As mats dehydrate and contract, the edges of polygons roll inwards to produce characteristic open dishes. These edges are particularly susceptible to erosion and transport - acting to ‘seed’ new mats if deposited in a suitable environment. #SabkhaSaturday

Closing date fast approaching 👇

Today👇

For today’s #SabkhaSaturday, we offer an accumulation of gastropods. Gastropods are abundant in lagoons adjacent to the Abu Dhabi sabkha. Postmortem transport concentrates them into beach ridges and spits. If preserved, these ‘gastropod rudstones’ would confuse palaeoenvironmental interpretation. ⚒️🧪

Working on #carbonate sediments? Brilliant! Well done you! But... only a few days left to submit you abstract for our session ‘#Carbonates - archives of time, space and change’ at #EGU24! meetingorganizer.copernicus.org/EGU24/sessio... @Sedimentology @EuroGeosciences @EGU_SSP ⚒️🧪

@earth-science.bsky.social ⚒️ Did you know that turbidity currents can flow below the sea bed? This happens when flow density is greater than mud bed density. These ultrasound images ⬇️ show the change of 'suprabed' (top) to 'intrabed' flow (bottom) in the Porto Alegre laboratory, Brazil. 🎄🎁🎅

Today’s #SabkaSaturday offering is this distinctive feeding bioturbation trace in the middle intertidal zone of the Abu Dhabi sabkha. This is formed by a Greater Flamingo standing at the centre and rotating on the spot as it feeds🦩⚒️

For this week’s #SabkhaSaturday, our offering is a rather nice example of metre-scale halite polygons in the supratidal zone of the Abu Dhabi sabkha. These features form through lateral displacement during halite precipitation.
