A combined team of researchers from the University of Cambridge and the University of California has found evidence that casts doubt on the use of zircon crystals as evidence of early development of the Earth's magnetic field. ...
Zircon crystals in igneous rocks must be carefully examined and not relied upon solely to predict future volcanic eruptions and other tectonic events, QUT researchers have shown.
