Abstract—The analysis of paleomagnetic data from Late Neoproterozoic complexes of Siberia and Australia is carried out. We show that the existing paleomagnetic datasets are in a disagreement with the concept of the axial-dipole configuration of the Late Neoproterozoic geomagnetic field: proposed non-actualistic models of the field do not reasonably explain the distribution of the paleomagnetic poles. We carried out analysis of paleomagnetic and virtual geomagnetic poles distribution based on simple geometric calculations. The analysis suggests that the configuration of the Late Neoproterozoic geomagnetic field was determined by the coexistence of a weak, long-lived source that was stably fixed in space, with a main dipole source that experienced sporadic multidirectional jumps within a certain preferred region of the Earth. Predominantly equatorial orientation of the main dipole source is substantiated by paleoclimate proxies. We propose a descriptive non-actualistic model of the Late Neoproterozoic geomagnetic field—the Devious Equatorial Dipole hypothesis, which brings paleomagnetic and paleoclimate data into accordance.

一个偏斜的赤道偶极子假说：关于晚前寒武纪低纬度冰川问题和地磁场配置

摘要——对西伯利亚和澳大利亚晚新元古代杂岩体的古地磁资料进行了分析。我们表明，现有的古地磁数据集与晚新元古代地磁场的轴偶极构型的概念不一致：提出的场的非现实模型不能合理地解释古磁极的分布。我们基于简单的几何计算对古地磁极和虚拟地磁极分布进行了分析。分析表明，晚新元古代地磁场的配置是由稳定固定在空间中的弱、长寿命源与在地球某个优选区域内经历零星多向跳跃的主偶极源共存决定的. 主要偶极子源的赤道方向主要由古气候代理证实。我们提出了晚新元古代地磁场的描述性非现实模型——偏斜赤道偶极子假说，它使古地磁和古气候数据相一致。
