HOLOCENE TUFA
with impressions of leaves


About 12,000 years old

Caerwys Tufa Quarry,
Clwyd, North Wales​​​​​​​


Tufa is a soft form of limestone that is primarily deposited by calcium-rich springs as the waters emerge from the ground. The tufa extracted at Caerwys Quarry was once used to make cement, and later widely used in alpine gardens, but in recent decades it has been the subject of scientific research.

The Caerwys tufa is thought to represent carbonate precipitation at the very beginning of the Holocene period and may shed light on the climate at the transition of the Late-glacial interstadial, Younger Dryas stadial and early Holocene. 

This little specimen is from an old collection. The quarry is now a designated Site of Special Scientific Interest as the only example in the UK of tufa formation during this period.
