Paleomagnetic evidence for a long-lived, potentially reversing martian dynamo at~ 3.9 Ga
The 4.1-billion-year-old meteorite Allan Hills 84001 (ALH 84001) may preserve a magnetic
record of the extinct martian dynamo. However, previous paleomagnetic studies have …

The “new core paradox”: Challenges and potential solutions
P Driscoll, C Davies - Journal of Geophysical Research: Solid …, 2023 - Wiley Online Library
The “new core paradox” suggests that the persistence of the geomagnetic field over nearly
all of Earth history is in conflict with the core being highly thermally conductive, which makes …

Statistical reanalysis of Archean zircon paleointensities: no evidence for stagnant-lid tectonics
The initiation of mobile-lid plate tectonics on Earth represented a critical transition towards a
more familiar world in terms of surface temperature stabilization, biogeochemical cycling …
