Cockercombe tuff

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]
