Local Magnetic Anomalies Explain Bias in Paleomagnetic Data: Consequences for Sampling
GEOCHEMISTRY, GEOPHYSICS, GEOSYSTEMS
02 may 2024
Romy Meyer, Lennart V. de Groot
Volcanic rocks are considered reliable recorders of past changes in the Earth's magnetic field. Recent flows, however, sometimes fail to produce th...
