摘要:

Palaeomagnetic measurements indicate that the uraniferous Radium Ridge Breccias near Mt Painter in the northern Flinders Ranges of South Australia have been magnetized twice, both times in the Permo‐Carboniferous. The palaeomagnetic south pole for one remanence was estimated as 165.1°E, 65.7°S (A95= 11.5°). The direction for the other remanence was not well defined; however samples collected from diamictite bodies within the breccia gave 133.9°E, 33.1°S (A95= 6.9°) as the probable pole for the overprint. The latter is similar to overprint poles published from central Australia, which are generally attributed to the Alice Springs Orogeny.
