Permo-Triassic boundary section in Meishan C Quarry. Beds numbered ready for sampling. Hammer shaft lies on Bed 25, an altered ash horizon, which has yielded zircons with an age of 252.4 Ma (Mundil et al., 2004). Previous analysis yielded a slightly younger U/Pb date of 251.4 Ma for this horizon (Bowring et al., 1998). (Photo copyright AD Saunders) |
