摘要
作者使用Thellier法、Shaw法和Van Zijl法测定了1986年4月15日落于湖北随州的属L群球粒陨石的古磁场强度。从7个样品中获得22～39μT、平均值为24.8μT、较一致的古磁场强度结果。陨石的一般磁性特征表明,磁性矿物分布均匀,并以低居里点(300～400℃)的成分为主。磁化率各向异性参数显示,陨石在形成过程中及其后,受到了一定的应力作用。
The palaeomagnetic field intensity of meteorites, belonging in the chondrite of L group, and falling down to the earth on 15th of April, 1986, in Suizhou, Hubei, has been determined by three methods ( Thellier method, Shaw method of ARM method, Van Zijl method of single-heating method ) . The palaeomagnetic field intensity of the meteorites is 24.8μT on an average. The magnetic feature of meteorites shows that magnetic ores are well distributed in the meteorites and the Curie temperature of the majority of magnetic ores is less than about 300-400℃, and the meteorites have suffered the stress action when they formed and after they formed.
