Thomsonite + Apophyllite
Moonen Bay, Isle of Skye, Scotland, UK
FOV approx 50cm across
A large pipe cavity lined with apophyllite and stalactitic thomsonite. The pipe is about 20cm in diameter. An unusual occurence; haven’t seen another one like it at Moonen Bay or elsewhere. Other cavities in the same boulder contain the same minerals, but in completely different habits to this single example.
