内容記述 | Ten rare earth elements (REE) (La, Ce, Nd, Sm, Eu, Gd, Tb, Tm, Yb and Lu) were determined by neutron activation analysis for 7 Antarctic meteorites (Yamato-74001,-74082,-74094,-74155,-74191,-74371 and Allan Hills-78084) and for three non-Antarctic enstatite chondrites (Abee, Indarch and Qingzhen). The Antarctic meteorites studied in this work show similar REE abundance patterns to those in C1 chondrite. Their absolute REE abundances are about 1.2 to 2.1 times higher than the C1's, but no systematic variations were confirmed in the REE abundances of bulk chondrites with petrologic types 3 to 6. Smooth patterns and uniform abundances of the C1-normalized REE's suggest that most of these Antarctic meteorites are free from alteration due to terrestrial weathering as for bulk abundances of the REE's. | |||||
