The correlation of acid volcanoes in the Archaean of Western Australia
This is the first extensive U-Pb geochronological study of volcanics from the greenstone belts of the Archaean Yilgarn Block.
Twenty three felsic samples of about 50 kg were processed for zircons and over forty zircon samples were analysed.
The isotopic results provide information on the uranium and thorium contents of the zircons as well as the age of the volcanic rocks.
Keywords: Archaean, Yilgarn, felsic volcanics, zircon.
