摘要:
K‐Ar age determinations on granites from Central Queensland support the conclusions of field mapping, that the intrusives of the Anakie High are generally older than the rocks of the Drummond Basin. Results on granites from the Bowen‐Collinsville region indicate that they pre‐date most of the Bowen Basin sediments. Four ages are reported for basement rock from bore‐cores in the Great Artesian Basin. They confirm Precambrian basement to the south of the Mt. Isa‐Cloncurry area, and suggest possible Precambrian in the Long‐reach Spur. Two samples from the Nebine Ridge give Lower Carboniferous results. A previous report of Permian basement in the Surat Basin has been shown to be incorrect.
