Outline of Final Research Achievements

In order to investigate large scale circulation of material inside the early solar nebula, we developed coordinated analytical method of meteorites, carbonaceous chondrites which especially most primitive class of the meteorites, using synchrotron radiation computed tomography (SR-CT). We developed sample holders, X-ray detector for the multi-scale tomography, data analysis program for multi-scale SR-CT and database for the
Using these devices and softwares, we could investigate more than 100 pieces of carbonaceous chondrites, and analyze the relation of chemical compositions and size of inclusions between carbonaceous chondrites, and investigate the formation environment of them in the early solar nebula statistically and quantitatively.
