| 内容記述 | Results form the Antarctic sample, LEW 86010 indicate that it is an extremely interesting meteorite of clear igneous origin, and is probably closely related to ADOR. Several important questions await further detailed study. The most stringent test of the relationship to ADOR will come from the measurement of the oxygen isotopic composition. One possibility proposed is that LEW 86010 represents a partial or total melt of a mixture of material similar to the white Allende clasts and more ordinary chondritic meteorite material. Several lines of investigation will contribute to resolve this question. Further melting studies will be performed to determine whether LEW 86010 represents molten lava. In addition to test the connection with Allende, isotopic studies will look for anomalous isotopic compositions which are ubiquitous in Allende white inclusions. All of these studies will be performed on a tiny sample which weights only 5 grams, and is smaller than a marble, but which contains important clues to events which occurred during the birth of the solar system. |
