Okada et al. (2006) reported average elemental mass ratios of Mg/Si = 0.78 +/- 0.09 and Al/Si = 0.07 +/- 0.03. In this study we attempted to estimate the upper limits of elemental mass ratios of Ca and Fe. The preliminary results are Fe/Si = 1.0 +/- 0.5 and Ca/Si = 0.09 +/- 0.04 respectively. Fe/Si likely indicates LL- or L-Chondrite composition, but a primitive achondrite such as Acapulcoite still remains. Meanwhile, Ca/Si reveals LL-, L- or H-Chondrite composition, but some primitive achondrites (Winonate, Aubrite) cannot be ruled out. Acalucoites and Lodranites are plotted out of the error bars.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
