Palaeomagnetic correlation of the Acraman impact structure and the Late Proterozoic Bunyeroo ejecta horizon, South Australia
Palaeomagnetic data for meltrock from the Acraman impact structure, South Australia, indicate a stable magnetization and a virtual geomagnetic pole that is in close agreement with the palaeomagnetic pole for the Late Proterozoic (˜ 600 Ma) Bunyeroo Formation in the Adelaide Geosyncline. The palaeoma...

Summary: | Palaeomagnetic data for meltrock from the Acraman impact structure, South Australia, indicate a stable magnetization and a virtual geomagnetic pole that is in close agreement with the palaeomagnetic pole for the Late Proterozoic (˜ 600 Ma) Bunyeroo Formation in the Adelaide Geosyncline. The palaeomagnetic data are therefore consistent with the correlation of the Acraman impact event and deposition of the widespread impact ejecta horizon in the Bunyeroo Formation. |
