A quantitative definition of accommodation: Implications for understanding and prediction of strata A rigorous quantitative definition of accommodation indicates less predictive power than typically assumed.

Curious about how accommodation can be rigorously defined and what a rigorous definition reveals? Check out www.science.org/doi/10.1126/... for some thoughts…

We still use CarboCAT actually, for example currently to study platform drowning geometries

Intriguing cross-cultural fact; British (pictured) versus US hash brown divergence. Think I prefer US version - better for soaking up egg and bean juice

Spontaneous spectacular floor find in the Newfield Inn, Seathwaite, Cumbria U.K. A laminated layer-cake of loveliness from the nearby Ordovician Seathwaite Fell Sandstone Formation. Toeset for scale

Exactly, Nefyn, Llyn Peninsula. And beach pebbles are from late Pleistocene fluvioglacial strata so a good regional sample

BGS Geology Viewer - The Geological Map Viewer of Britain Discover our geology with direct access to detailed information about the rocks all around you.

Does look like some form of chert? Check out the location on geologyviewer.bgs.ac.uk?_ga=2.246941... - geocontext always helps ID

Best guess IDs: Bottom row probs granodiorite and porphyritic andesite. Middle row Carboniferous Limestone with coral, perhaps Siphonodendron, Lithostrotion etc, and Ordovician mudstone with thin turbidites. Top left felsic mylonite, top right right probs mafic mylonite

Six pebbles from Nefyn Beach, two igneous, two sedimentary and two metamorphic

You have to love a pebbly beach, but especially one with a great range of igneous, sedimentary, and metamorphic rocks 😍

A mylonite beach pebble, a 600 My old microcosm of plate tectonics

A little bit of sheared and folded Neoproterozoic schist from Anglesey, Wales, a great place to understand how complex orogeny can be

It’s a good example of problems arising from presenting useful-but-dumb algorithms as intelligent when they are very definitely not

Here’s a motivational limerick I created for reluctant stereonet users

Apparent cyclicity in strata, and the process of determining if it really is ordered-cyclical or just randomly repetitive, is one of my favourite things. This example is Pennsylvanian deltaic? strata at Amroth, South Wales, with logging Liverpool University students for scale

Indeed, different kind of plate boundary in the two locations, but squishing is still squishing 😉

Too cool to be gneiss, this site is strat-tastic 😉

Folded upper Carboniferous strata

Because you cannot beat a good fold 😍 especially examples like this that show complex 3D geometry

Wall of the week; crinoids! And possibly stylolites dissolving them. Beautiful 😍

Deepest winter sunshine

The coral kerbstones of Amsterdam

A marbleously metamorphic Wall of the Week, Dam Square, Amsterdam

A few days post SEPM research conference to revisit some classic cratonic stratigraphy in a breathtakingly beautiful location 😍

Clunky code is fine of course, whatever works, means-to-an-end etc, but there are few things more satisfying than elegantly efficient code 🤓 Mostly as an aspiration however 😉

Jurassic water park?

Interested in how autogenic processes can make an allogenic input signal indistinguishable in submarine fan strata? Details in a new open-access EPSL paper here authors.elsevier.com/sd/article/S...

Any idea what that would look like when “deposited”?

Very well deserved 👏

I think you just succinctly summarised most social media 😉

Surely @makingripples.Baku.social entirely transcends the crude concept of age? 🤔

Need to go and see these outcrops - I came, I saw, I modelled
