The Ediacaran features an instable magnetic field complicating paleogeographic reconstructions; a new paleointensity study on late Ediacaran rocks indicates a weak but stable dipolar field.
New data on ancient burnt structures is integrated into a superior spherical cap field model for Europe.
A 200-year resolution record from the Black Sea for marine isotope stage 6 (130-180 ka) shows a stable geomagnetic field.
A new study extends the calibration of the Mesozoic Sequence down to the Mid Jurassic with multiscale marine magnetic anomaly data, demonstrating extraordinarily high reversal frequency.
Magnetic studies offer a new strand for the analysis of faulting processes and could help with better understanding of fault rupture and earthquakes.
Classic interpretation of aeromagnetic anomaly maps involves several steps with limiting boundary conditions; a recent study develops convolutional networks largely bypassing these issues.
Various unmixing approaches are used in environmental magnetism, each starting from a different premise; now they are put to the test by scrutinizing experimental mixtures of known endmembers.
In classic paleomagnetic data processing uncertainties are calculated at a single level only, but there is now a more lucid way to include error propagation.
Small amounts of polar wander have occurred during geological history, but whether larger amounts occurred is still controversial. Did a truly large polar wander event really happen?
