内容記述 |
Four new Antarctic iron meteorites collected at Yamato meteorite ice field in 1979,Yamato-790517,-790724,-791076 and -791694,are magnetically analyzed. Characteristics of their magnetic hysteresis curves and thermomagnetic curves indicate the following meteoritic structures of these iron meteorites. Yamato-790517 is a Ni-poor ataxite consisting of kamacite matrix of 6.4 wt% Ni, unequilibrated Ni-rich kamacite specks of about 12 wt% Ni and taenite specks. Yamato-790724 is a coarse octahedrite of kamacite matrix of 7.0 wt% Ni and taenite specks. yamato-791076 is a finest octahedrite or an ataxite which consists of kamacite of 7.3 wt% Ni and plessite of about 12 wt% Ni. Yamato-791694 is a Ni-rich ataxite consisting mostly of taenite of about 40 wt% Ni and a small amount of kamacite specks. Two Antarctic iron meteorites collected near Allan Hills in Victoria Land in 1977,Allan Hills-77263 and -77289,also are magnetically analyzed. Both the iron meteorites are coarse octahedrites comprising kamacite matrix of about 6.5 wt% Ni and taenite specks. |
