Three types of internal texture are observed in Ni-bearing I-type spherules: Ni free Fe oxide mantle with Fe-Ni metallic core, Fe-Ni oxide mantle with Fe-Ni metallic core and Fe-Ni oxide spherules without metallic core. Numerical simulation was performed in order to estimate variation of temperatures and radii of I-type spherules, and the force of inertia exerted on them entering the atmosphere. From the result of the simulation, it is figured out that spherules lose more than 90 percent of their original mass by ablation over 1,900 C and that the force of inertia is maximum at last stage of evaporation. Based on the observations of I-type spherules and the numerical simulation of their formation, we propose a model of the formation process of I-type spherules: during ablation, metallic core is off-centered, then surface of the core is exposed to the air due to the strong force of inertia and oxidation reaction might proceed from the exposed core surface.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
