Chinese Swamp Core Reveals 47,000 Years of Monsoon History
Magnetic analysis of mineral composition supports the importance of tropical climate processes in shaping long-term monsoon patterns.
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.
