 note = {As a part of a consortium study, we analyzed the Martian meteorite Yamato (Y) 000097 by prompt gamma-ray analysis, instrumental neutron activation analysis, and instrumental photon activation analysis. For comparison, we also analyzed Allan Hills (ALH) 77005 using the same methods. The data confirm that Y000097 belongs to lherzolitic shergottites in terms of chemical composition. Although there exist slight differences in elemental abundances among lherzolitic shergottites due to differences in the modal abundances of constituent minerals, they have essentially the same chemical compositions, suggesting they are genetically related and experienced similar formation histories.Zr/Hf ratios obtained for Y000097 and ALH 77005 are subchondritic, consistent with values reported for other lherzolitic shergottites and olivine-phyric shergottites. Such fractionation can be explained by invoking clinopyroxene, ilmenite, or majorite in the petrogenesis of the shergottites' source material. CI-normalized Hf/Sm ratios obtained for Y000097 and ALH 77005 are 1.52 and 1.37, respectively, consistent with superchondritic Hf/Sm ratios reported for shergottites. Based on experimentally derived partition coefficients, majorite is the best candidate mineral for the fractionation of Hf and Sm in shergottites., 即発ガンマ線分析法、機器中性子放射化分析法、機器光量子放射化分析法を用いて、南極で見つかったレールゾライト質シャーゴッタイトYamato 000097の分析を行った。鉱物組成の割合のためレールゾライト質シャーゴッタイト間で化学組成に微かな違いが見られたが、どのレールゾライト質シャーゴッタイトも同じような化学組成の特徴を示しており、レールゾライト質シャーゴッタイトは同様な形成過程を経てきたと考えられる。Yamato 000097のHf/Sm比は、他のシャーゴッタイトと同じ比であり、コンドライトより高い値であった。シャーゴッタイトの化学組成と実験系で求められた分配係数より、シャーゴッタイト中のHfとSmを分別させた火成活動には、メージャライトが関わったものと考えられる。},
