Extended Data Fig. 7. An olivine crystal and the surrounding phyllosilicate-rich matrix in the rare olivine-bearing grain A0104–02403200.
(a) BF-TEM image of radiation-damaged olivine and highly porous hydrated matrix in the cross-section sample A0104–02403206, which was prepared from A0104–02403200. (b) Low-angle annular dark-field (LAADF)-STEM image shows that the olivine contains solar flare tracks indicated by arrows as well as dislocations (Disloc) and a radiation damage layer. (c) BF-TEM image shows that a thin (~20 nm) continuous smooth layer covers the phyllosilicate-rich matrix of the cross-section sample A0104–02303204, which was prepared from A0104–02403200.
