Busy day with @UoM_EES 1st years! Amongst other tasks: describing folded Cambrian pillow basalts at Llanddwyn (which way is up in the photos?!), measuring the vertical atmospheric temperature profile & cataloguing invertebrate fossils in the Carboniferous limestone at Benllech.

The recent storm seems to have flushed acid mine water from old coal mines through Skewen. Pretty nasty stuff, and dreadful for the environment, apart from the obvious property damage.

To muck in with @tectonictweets #RandomFieldworkPhoto , it would be impossible to locate this one from last summer (although guesses welcome). However, can anyone guess the age of the rocks? @raduller and Pete Wooldridge for scale.

Beneath it, the Cretaceous & the world of the Dinosaurs. Above it, the Cenozoic & the rise of the Mammals. The airfall layer is succeeded by a coal. Possibly it's fine-grained nature formed an impermeable, poorly drained layer that ponded water & promoted peat accumulation.

These photos are great for picking out the detail! Bottom two during extension: fantastic rift topography generated in bottom right by cohesive flour. Top right: a kind of continental margin style tectonics by extending the inverted topography. Top left: erm... complex!

Interesting study into the real possibilities of generating "renewable" energy by pumping water from legacy deep coal pits. I find the very real potential of a diverse renewable energy mix back in Wales very interesting...

Britain’s coal-powered past may still have an important role to play in its green future. A paper published in QJEGH by a team led by Gareth Farr from @BritGeoSurvey addresses the issue of what to do with Britain’s coal mines. Read the blog here:

Rock of ages: how chalk made England

The long read: Swathes of England’s landscape were shaped by the immense block of chalk that has lain beneath it for 100 million years. For a long time, even geologists paid it little heed – but now...

The paper uses unbelievably well exposed shallow water delta mouth bar deposits to show how they evolve intrinsically in a much more complex way than simple vertical aggradation and lateral expansion. Flume tank experiments have shown this before. Click below for a surprise!

2nd year @UoM_EES students making density flows using different salt water solutions. Lovely head developed in the red experiment (38 permil NaCl=1,020 kg/m3). Overall bed roughness is not quite enough to induce large amounts of turbulence & mixing. Will fine tune for next time!

Is nobody concerned that barring travel from Europe to the USA apart from via the UK (in what can only be a thinly veiled and psychophantic life line to the UK economy) effectively invites us to become a corridor and haven for infection?
