Area: 0.8 hectares.

Description and Reasons for Notification: 

An important exposure of lamprophyric lava belonging to the poorly-exposed Exeter Volcanic Series which outcrops in this locality. The rock is an olivine-biotite phyric minette characterised by potassium enrichment and high levels of strontium, barium and light rare earth elements. The lava is representative of the high-level post-orogenic vulcanicity that occurred in localised graben structures and characterised south-west England during the early Permian.
