i A re‐examination of the palaeomagnetism of the Older Cainozoic Volcanics of Victoria has indicated that these rocks possess temporary unstable components of magnetization. Thermal demagnetization experiments show the magnetic mineral in these basalts is a titanomagnetite. A.c. cleaning experiments to remove the unstable components of magnetization are also described.
