Abstract
In a recent paper [1] we presented U, Th and Pb data for both mineral separates and total rocks for two crystalline rocks from the Apollo 14 mission. In that study we established for the first time the following major points: (1) U-Pb internal isochrons for two rocks. (2) Demonstration of the presence of initial radiogenie Pb. (3) Explicit demonstration of the cause of the apparent disagreement between the different methods of age determination and a possible means of experimentally reconciling this discrepancy in general. (4) The most direct estimate yet made of the "age" of the moon (or lunar crust). (5) A new diagram for representing U-Pb data which explicitly emphasizes initial Pb and which is analogous to the Rb-Sr evolution diagram.
