Paleomagnetic and K-Ar dating studies of Late Cretaceous basaltic dykes intruding Late Permian sediments of Newcastle Coal Measures,Newcastle, Australia-Relationship to the opening of the Tasman Sea
Paleomagnetic studies of Late Cretaceous basaltic dykes (K-Ar age of ca. 80Ma) and associated sediments reveal the presence of both normal and reverse polarity magnetizations. Correlation with the geomagnetic polarity time scale shows that the normal polarity magnetization could have been acquired i...
