Nb/Zr fractionation on the Moon and the search for extinct Nb-92
A comprehensive Zr isotopic study was conducted on eleven lunar basalts and highland rocks to search for evidence of the extinct nuclide 92Nb, which decays to 92Zr with a half-life of 36 Ma. Internal isochrons were determined for two early highland rocks, 77215 and 60025. No resolvable Zr isotopic v...
