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.

What Shaped the Northern Apennine Deformation Front?
An integrated interpretation of well and seismic reflection data from Italy’s Po Valley shows the range’s undulations are controlled by the slope and composition of two major gliding horizons.
