内容記述 | The stability of natural remanent magnetization (NRM) of various chemical groups of meteorites, which have been carefully recovered from the Antarctic ice sheet surface, is examined against the AF-demagnetization. The meteorites examined are 1 E-chondrite, 3 H-chondrites, 5 L-chondrites, 2 LL-chondrites, 3 C-chondrites, 4 achondrites, 3 irons and 1 pallasite. In general, the AF-demagnetization stability of NRM's of C-chondrites and achondrites is sufficiently high to be attributed to the natural remanence acquired in the extraterrestrial space. NRM of 3 irons also is reasonably stable, but the NRM is very likely to be attributable to TRM acquired in the geomagnetic field on entry into the earth's atmosphere. NRM's of E-, H-, L- and LL-chondrites and pallasite are much less stable compared with those of C-chondrites and achondrites. It cannot be recommended, therefore, to use those meteorites having poor stability of NRM for the paleointensity research purpose. | |||||||
