Area: 1.9 hectares. 

Description and Reasons for Notification: 

This site exposes potassium-rich lavas of Permian age, the lavas being massive amygdaloidal trachybasalts with an irregular rubbly top to the lava flow. This is one of the few localities where the extrusive environment of the Permian lavas can be demonstrated. Part of the quarry is in an intimate sediment-lava “melange” with interrelationships that suggest the lava flowed over and penetrated wet sediments, variously entrapping baked sediment within an open lava network.
