【摘要】 通过测量姜寨遗址窑灶烧土标本的剩余磁化方向,确定了公元前四千年左右该遗址所在临潼地区的地磁场方向(倾角和偏角),采用逐步热退磁法,求出了当时、当地的地球磁场总强度值。由此,按照中心偶极模式算得了当时该地区所在的地磁纬度,以及该时期的虚地磁极位置和地球的虚偶极矩。更多还原

【Abstract】 Some new results of archaeomagnetic research on the baked earth specimens from Jiangzhai relic of neolithic age are reported in this paper. The direction of the geo-magnetic field at about 3900 B.C. in Lingtong region where this relic is located was determined. The position of the virtual geomagnetic pole for this period were deduced according to the geocentric dipole model. The paleo-intensity was determined by using the Thellier method. The virtual dipole moment (VDM) and the corresponding reduced dipole moment (RDM) were also calculated for this epoch.更多还原
