Yeah, that's the picture I got from the screed, too, JonF, and I have only 1st year geology for arts geeks. The entire field is contaminated with rocks of differing ages, making isotope-dating pretty much impossible.
Even if they can prove the contamination by xenoliths in every single igneous rock bed ever isotope-dated, everywhere in the world, all that proves is contamination, and the need to separate out xenoliths before dating methods are applied (if that's even possible).
Still not support for any young earth claims.
