U and Pb isotopes and rare earth elements (REEs) of phosphate grains in three H-chondrites of different petrologic types were measured by the SHRIMP instrument. The observed ages of 4554+/-39 Ma (2sigma) of Y-7301 (H6) and 4535+/-120 Ma of Y-74371 (H4) are consistent with previous work using TIMS. In contrast, those of 4084+/-350 Ma of ALH-77294 (H5) is apparently younger than previous study on other H5 chondrites, suggesting that the U-Pb system was affected by secondary thermal event such as an impact heating. Observed isotopic compositions of common lead of these chondrites indicate that model age using the Pb composition of Canyon Diablo FeS as initial lead might not be valid for some Antarctic meteorites. The REE abundance patterns of the whitlockites normalized to Cl chondrite are characterized by an almost constant enrichment at 200-400 times higher than Cl chondrite, and a striking negative Eu anomaly. The REE abundances of the apatites are lower than those of whitlockite grains, and vary appreciably among different grains. The significant correlation between the Eu anomaly (Eu/Eu*) and concentration of REE is confirmed. (C) 2002 Elsevier Science B.V. All rights reserved.
