A 200-year resolution record from the Black Sea for marine isotope stage 6 (130-180 ka) shows a stable geomagnetic field.
Magnetostratigraphy
Uncertainty Propagation in Paleomagnetic Data Quantified
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.
Challenging the Day Diagram, a Rock Magnetism Paradigm
A critique of the plot routinely used to determine bulk magnetic properties concludes the technique is so ambiguous that new approaches to understanding magnetic mineral assemblages must be developed.
