This report provides a summary of high precision chemical abrasion - isotope dilution thermal ionisation mass spectrometry (CA-IDTIMS) U-Pb geochronology which has been performed on zircons from three samples taken from the eastern Gawler Craton. The samples are representative of Hiltaba Suite granites of the Tickera Granite body exposed at Point Riley, north-western Yorke Peninsula. Sample 2166262 is a foliated quartz-syenite with an emplacement age of 1584.22 ± 0.83 Ma. Sample 2053555 is a weakly foliated leucotonalite that intrudes the quartz-syenite and has an emplacement age of 1582.66 ± 0.61 Ma. A third sample from an undeformed miarolitic alkali-feldspar granite dyke that cuts the two earlier phases was intruded about 3.5 million years later, at 1579.05 ± 0.53 Ma. The results now obtained by using this new high precision geochronology method demonstrate that ductile deformation in this portion of the eastern Gawler Craton occurred after c. 1584 Ma and was synchronous with emplacement of the Tickera Granite at c. 1583 Ma. These dates demonstrate that magmatism in the Gawler Craton continued for a period of up to 8 to 10 million years after the eruption of the Gawler Range Volcanics, an event which occurred c. 1594.5–1586.5 Ma (Jagodzinski et al. in prep).
