Our paper on sole marks, the world's most unloved sedimentary structures, is now formatted (a mere 65 pages!) and open access https://t.co/MrTUzdOUL2 Do not be afraid, it has wonderful figures, including a new Bouma Sequence diagram..

[Jeff Peakall @hyperpeaknal]

I don't like this place anymore and particularly its owner so am off to the other side where it seems I am almost the last to arrive... It was fun for a while!

[Jeff Peakall @hyperpeaknal]

@dinojonrox Are there any other process sedimentology sculptures out there?

[Jeff Peakall @hyperpeaknal]

@dinojonrox Enjoy. Great to see you, a delight as always. Your talk today was one for the ages!

[Jeff Peakall @hyperpeaknal]

@dinojonrox @brit_seds Looking forward to them!

[Jeff Peakall @hyperpeaknal]

@Making_Ripples @BeneskiMuseum @geology_johnson Stunning. Rippling over sands for top left. Then presumably there was a mud coating over the interference ripples before infilling with sands to give the other two surfaces - presumably soles of beds infilling interference ripples.

@MikeAClare Ouch!

What a cover image! (though I may be biased)

New paper by @mzakizulkifli in EPSL exploring what controls different types of erosion in submarine channels based on repeat seafloor surveys w @hyperpeaknal @ChannelWidth @sedimorph @MaartenHeijnen & co @NOCnews @NRCan @unisouthampton @DurUniEarthSci https://t.co/R2Dh1IYi1Z

A stunning image of FIDS from @KHwave. An example of 'dinosaur leather'. This has been quite the voyage of discovery! Sounds like quite a volume as well.

[Jaco H. Baas 🇪🇺🏴󠁧󠁢󠁷󠁬󠁳󠁿🇳🇱⚒️⛰️🌊🚶🥘🎶⚽ @Making_Ripples]

Watch out for the October issue of @JSedimentology, with a State of the Science paper on FIDS (stunning cover image by @hyperpeaknal ⬇️), and further papers on dolomite, microbes, submarine channels/canyons, deep lakes, point bars, and more. @sedimentology

Study leave 2024 - first field day in deep-marine Cloridorme Fm. FIDS, mud ripples and frondescent marks galore.

[Jeff Peakall @hyperpeaknal]

Our new State of the Science paper on sole structures - the catchily named Flow-induced Interfacial Deformation Structures (FIDS) is now out in Sedimentology: https://t.co/QTVZqXaeOF
with @KHwave @Making_Ripples @stratleeds Paul Wignall and Piotr Lapcik. Here is a taster...

[Jeff Peakall @hyperpeaknal]

@Making_Ripples Enjoy!

[Jeff Peakall @hyperpeaknal]

Part 2 of our planned Trilogy on sole marks is coming imminently. These largely forgotten structures provide us with lots of information on the flows that formed them! With @KHwave @Making_Ripples @stratleeds and more.

[Jaco H. Baas 🇪🇺🏴󠁧󠁢󠁷󠁬󠁳󠁿🇳🇱⚒️⛰️🌊🚶🥘🎶⚽ @Making_Ripples]

NEW PAPER ALERT: Continuing the reinvention of sole marks, and extending their use beyond palaeoflow reconstruction. Led by @hyperpeaknal and soon out in @JSedimentology.

[Jeff Peakall @hyperpeaknal]

Well worth a read! With the brilliant @Naughty_Onlaps and @stratleeds

[Sedimentology @JSedimentology]

Need to fill the time before the start of @IAS_Aberdeen ? Why not read ' Evolving fill-and-spill patterns across linked early post-rift depocentres control lobe characteristics: Los Molles Formation, Argentina'
