1.费歇分布古地磁采样可在几个样品产地进行,每地采一至几块样品,每个样品切成一至几块标本,分别测其剩余磁化方向.整理数据时,先由每块标本的磁化方向求样品磁化方向的平均值,再由样品的平均值求样品产地平均值,最后由样品产地平均值求岩石单元的平均值.为求每级磁化方向的平均值,需有一种方法对一组向量进行统计分析.每一磁化方向用单位长度的向量表示;磁化强度较大的样品不加权.
1. Ferocious distribution of ancient geomagnetic sampling can be carried out in several samples of origin, each picking one to several samples, each sample is cut into one or several specimens, respectively, measured the direction of residual magnetization.Finishing data, the first by each specimen Of the magnetization direction of the average value of the sample magnetization direction, and then the average value of the sample obtained by the average origin of the sample, and finally the average value of the sample produced from the average unit of rock units for each level of magnetization direction of the average, there is a need A set of vectors are statistically analyzed, each magnetization direction expressed as a unit length vector, and samples with greater magnetization are not weighted.
