Present techniques for obtaining palaeomagnetic intensities can fail to detect mineral alteration occurring during heating in the laboratory. It is very likely that this alteration is responsible for much of the poor reproducibility of ancient intensities of the geomagnetic field. A technique is described which can detect it, with a significant improvement in both the reproducibility and accuracy of the results.
