We have conducted a rock magnetic and absolute paleointensity determination of the red dacite of the Duffer Formation of the Pilbara craton, Australia. The age of the dated rock unit is 3452 Ma +/-16 Ma. Vector analyses of step-wise alternating field (NRM up to 100 mT) and thermal demagnetization (from NRM up to 650 o C) results yield three components of magnetization.
