| A BO chondrule usually has an olivine rim that covers the chondrule surface. |
| The chondrule contains olivine, metal and intersitial mesostasis. |
| The relationship to the chondrule solidification textures was not clear. |
| This technique enabled the researchers to study the orientation and position of individual micrometre-sized grain particles that had coalesced around the chondrule. |
| However, radiative heating of whatever origin, including possible lightning, remains a candidate process of chondrule formation. |
| Although these LL chondrites have brecciated and metamorphosed textures, remnants of chondrule are present. |
