Quick Question - Quarries?

Hi Ruth; nice to see you here again too; and Sue too of course.

York Minster, which seems to have been re-built countless times, was built as we see it now from magnesian limestone quarried from Tadcaster. This stone was formed during a drying up of an inland sea with other deposits added over it during the Permian Period. The stone from the south in the other cathedrals being formed during the Jurassic Period which Dorset's unique coastline is noted from. Thus cathedrals are revealing a bit of the geology of England after the last ice age as it broke off from Continental Europe ( the River Thames once ran into the Danube in Germany) as glaciers retreated and various deposits were being formed.

Dorset's famed arch, Durdle Door will one day have the centre of the arch collapse and become two stacks instead like examples of stacks along our coast that began as arches as well.
