If the Moon formed prior to 4.51 Ga, why is there no variability in 182W in mare basalts in spite of the wide range in Hf/W ratios of their sources?
I guess, this is because final LMO crystallisation and lunar mantle overturn occurred after 182Hf became extinct. This is what is at least suggested by 146Sm-142Nd patterns in mare basalts. Happy to discuss this further in the Q&A.
