Cockercombe Tuff is a greenish-grey, hard pyroclastic rock, formed by the compression of volcanic ash containing high quantities of chlorite, which gives it its distinctive colour. [1] [2] It is found almost exclusively in the south-eastern end of the Quantock Hills [3] near Cockercombe, Somerset, England, from where it has been quarried for centuries.
Quantock Lodge is built from Cockercombe tuff. [4] [5]
