Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, The CO3 chondrite shows a similar thermal metamorphic sequence to those of ordinary chondrites and it is generally thought that thermal metamorphism of CO3 chondrites occurred in its parent body. We studied whether thermal metamorphism occurred in the parent body or in the primitive solar nebula by analyzing Fe-Mg zoning of olivine in the Yamato-791717 CO3.6 chondrite. Our results suggest that thermal metamorphism of the chondrite occurred in its parent body, being consistent with those of petrologic and mineralogical study., 資料番号: AA0065116010}, publisher = {宇宙航空研究開発機構宇宙科学研究所 (JAXA)(ISAS), Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)}, title = {The period of thermal metamorphism of Yamato-791717 CO3.6 chondrite by analysis of Fe-Mg zoning of olivine}, volume = {43}, year = {2010} }
