Outline of Final Research Achievements |
The Nice model predicts the possibility that the fragments of Edgeworth-Kuiper belt objects (EKBO) are present in the regolith of outer asteroid bodies. In this study I paid attention to foreign clasts in regolith brecciated meteorites and analyzed them using optical and electron microscopy, EPMA, Raman spectroscopy and synchrotron XRD. I could not discover possible EKBO materials, but found aqueously altered enstatite chondrites in Kaidun meteorite and discussed the possibility of the origin of earth water.
