How Prees' rocks inform scientists about Climate Change
whitchurchherald.co.uk
THE rocks beneath Whitchurch and Prees have been helping scientists to understand secrets about what the UK’s environment might have been like…

Exquisitely preserved Psiloceras from the Planorbis zone. Original aragonite shell still visible! @JET_Prees @icdpDrilling

Good work @icdpDrilling @JET_Prees team! The 656 m deep borehole finally cored Triassic-Jurassic boundary strata with overall high core quality and recovery very good to excellent! @NERCscience @CambSchMines @GSI_Exeter #Jurassicrocks #FossilFriday

Indeed!
Wow. The Prees outlier, Shropshire. I first read about this in Arkell’s Jurassic System in Great Britain. Memory’s rusty bit succession goes as high as Pliensbachian @JET_Prees ?

And here it is... the Triassic Jurassic Boundary in the @JET_Prees @icdpDrilling borehole (the pale grey layer 14cm in from the left!). Merry Christmas to all! (Photo stitch by Dominika Szűcs)

With coring complete @JET_Prees @icdpDrilling we are wrapping up with downhole logging. Some festive weather as well!

It might have been wet but the wait was worth it for @JbriJames and I. Look at these beauties! @icdpDrilling @JET_Prees

The glamorous side of scientific drilling: waiting in the sheeting rain as the next core is about to appear @JET_Prees @icdpDrilling

A full core barrel being taken out of the Prees borehole which is now drilling the Hettangian at around 520 metres! @JET_Prees

A new dawn at the @icdpDrilling @JET_Prees drill site: top drive was fixed, drilling depth now at about 510 m. 81 cores so far. More lovely grey mudstone, ammonites suggest we are in the upper Hettangian, on the way towards Triassic. https://t.co/IFsSMVZeE4

Some of the fruits of our labour @JET_Prees - Steve Hesselbo with the latest pallet of cores ready to go to the BGS core lab.

Really nice intraclast of laminated rock in the most recent core of Hettangian rocks from the prees borehole! @JET_Prees
