Caddo County IAB iron meteorite includes silicate inclusions rich in Na-rich plagioclase and diopside, which is classified as andesite. The andestic material can be an early partial melt product of chondritic materials. This indicates inhomogeneous segregation of partial melt of andesitic silicate and Fe-Ni-S metal from chondritic source occured even in a small planetesimal. This further implies that building block of terrestrial planets are not only chondritic materials, but also such inhomogeneously segregated partial melts from chondritic sources. Thus, the physical mechanism of metal segregation under microgravity, low pressure, and low oxygen fugacity needs to be understood, in order to decipher the abundances and partitioning behaviors of chemical compositions of the terrestrial planets. We plan to experimentally verify our model for the segregation mechanism of metal and silicate liquids on the microgravity planetismal., 形態: カラー図版あり, 共催: 日本学術会議, Physical characteristics: Original contains color illustrations, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113106},
