| sample_remark | Fanning & Link (2008): In general terms, Sturtian sections across South Australia contain a series of diamictite layers that have interbedded silts (e.g. Link and Gostin, 1981) and these have highly prospective layers that we consider to be tuffaceous or volcaniclastic in origin. West of Copley in northern South Australia, a tuffaceous bed in the lower Wilyerpa Formation, Yudnamutana Subgroup, Umberatana Group has a dominant igneous age component at ca. 659 Ma. This tuffaceous horizon is within the Wilyerpa Formation that comprises heterogeneous bedded diamictite, sandstone and siltstone containing ice-rafted debris, across the central and northern Flinders Ranges. At Copley, dropstones are abundant in the Wilyerpa Formation above and below the tuff bed. This 659 Ma age constraint on the Sturtian glaciation is consistent with Re-Os ages on post-Sturtian glacial black shales from Tindelpina Member of Tapley Hill Formation South Australia (643 +/- 2.4 Ma; Kendall et al. 2006) and Aralka Formation, Central Australia (657.2 +/- 5.4 Ma). |
