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)
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
