In this paper, different leaching procedures were used for the chondrules and chondrule fragments of Semarkona, and the U-Th-Pb compositions of leachates and residues were analyzed by TIMS method. The residues normally give higher 206Pb/204Pb ratio, suggesting higher radiogenic Pb compositions. These residues form a Pb-Pb isochron, and give an age of (4566.9±5.8) Ma with MSWD of 26, consistent to the weighted average age of 207Pb/206Pb model ages.
