"think the majority of Derbyshire is gritstone, not limestone, but there is limestone near Buxton"

There's a large amount of limestone in the southern Peak District ( the White Peak), and to the south of Buxton are a number of large aggregate quarries still busy extracting it. The wagons loaded with limestone are frequently encountered on the roads around the town. Try taking the A6 from Buxton to Bakewell to see the dramatic effects of this industry.

Arbor Low stone circle is made up of limestone, and the reefs make the distinctive hill scenery.
