They are using cosmogenically generated isotopes for dating. The error associated with their problems is related to the production rate of the isotopes in question.

K-Ar is less preferred than Ar-Ar dating. Same system, different method (I was trying to keep it simple).

Let's say you have a zircon crystal, it readily incorporates Uranium 238 and U235 into its crustal lattice because U has similar properties to the other elements in its formula. When U238 decays, it produces Pb207 and when U235 decays, it produces Pb206. Pb is not suitable in the crystal lattice and will be expelled from the crystal if the lattice is opened during heating.


That is the reason we love using zircons, because it takes a lot of heat to get rid of the Pb. So it is a great system. You don't get lunar zircons due to the mineralogy of the rocks.

If the moon doesn't have zircons, then whiskey tango foxtrot does this have to do with the issue?

Here, let's switch gears a little.

No thanks, I'm not fond of red herring.

Because you said you were incapable of comprehending lead-loss

"No thanks, I'm not fond of red herring."

Could have fooled me.
