The onset and nature of the earliest geomagnetic field is important for understanding the
evolution of the core, atmosphere and life on Earth. A record of the early geodynamo is …

The time scale for marine magnetic anomalies for the Late Cretaceous through Neogene (C-
sequence) and Middle Jurassic through Early Cretaceous (M-sequence with deep-tow …

The geomagnetic signal contains an enormous temporal range—from geomagnetic jerks on
time scales of less than a year to the evolution of Earth's dipole moment over billions of …

In this study, we examine the role of palaeosecular variation (PSV) in the use of statistics for
palaeomagnetic studies, and we provide new reliability criteria for palaeomagnetic poles or …

Twenty-five years ago, initial plans for reconstructing the Rodinia supercontinent were being
drafted, based on the growing recognition of correlatable mid-Neoproterozoic (0.8–0.7 Ga) …

The Earth's inner core grows by the freezing of liquid iron at its surface. The point in history
at which this process initiated marks a step-change in the thermal evolution of the planet …

The interval from the late Mesoproterozoic to early Neoproterozoic is generally considered
as a critical time for the amalgamation of Rodinia. The location of the North China Craton …

Although it is known that the geodynamo has been operating for at least 3.2 Ga, it remains
difficult to infer the intensity, dipolarity and stability (occurrence of reversals) of the …

It is now widely thought that geomagnetic polarity reversals occur spontaneously as a result
of normal dynamo action rather than being externally triggered. If this is the case, then it may …

A paleogeographic affinity of the south China craton (SCC) with India in the Neoproterozoic
has long been advocated based on lines of geological evidence. However, the lack of …
