| Outline of Final Research Achievements |
We have investigated the external shape and internal structure of chondrules contained in Allende meteorite, to reveal the chondrule formation mechanism. We measured about 100 chondrules and found 15 chondrules, which can be considered to be completely molten once. We compare the obtained relationship between the size and the shape of those chondrules with the theoretical relation that is obtained assuming the gas-frictional heating. Then, we have found that those two relations are consistent each other. This implies that the chondrules in Allende meteorite were exposed to the gas flow when they were molten.
