英文摘要	Miller Range (MIL) 05035 and LaPaz Icefield (LAP) 02224 are unbrecciated lunar basalt meteorites. In this report, we studied their petrography and mineralogy and made in situ uranogenic Pb/Pb dating of Zr-rich minerals. Petrography and mineralogy of these two lunar meteorites are consistent with previous investigations. The zirconolite Pb/Pb age of MIL 05035 is 3851 +/- 8 Ma (2 sigma), in excellent agreement with previous reports. This age suggests that MIL 05035 could be paired with Asuka 881757, a low-Ti mare basalt meteorite. The magmatic event related to MIL 05035 was probably due to the late heavy impact bombardment on the moon around 3.9 Ga. One baddeleyite grain in LAP 02224 shows a large variation of Pb/Pb age, from 3109 +/- 29 to 3547 +/- 21 Ma (2s), much older than the whole-rock age of the same meteorite (similar to 3.02 +/- 0.03 Ga). The other baddeleyite grain in LAP 02224 has an age of 3005 +/- 17 Ma (2s). The result indicates that the minimum crystallization age of LAP 02224 is similar to 3.55 Ga and the younger ages could reflect late thermal disturbance on U-Pb system.
