Yes, yes... it was a tricky sample. They knew that from the start. Eventually they flew in an expert, got a good sample, and a good date. It took 30 seconds to look this up and clear it up. You can better than this. hmmm.... prolly not, actually, given what you've posted so far.

But more importantly, it doesn't matter anyway because the clocks are reset by such things as heat. It is for this reason that people date lava flows, for example. The heat of the eruption resets the clock.
