The elusive snowball earth: U-Pb zircon ages from the upper diamictite of the Gifberg Group, South Africa

Results are similar to other glacial deposits in the region (further north, in Namibia). In total, sedimentological observations and detrital zircon age populations point to a large catchment area, characteristic of glacial events of regional significance. However, direct regional correlation is still not possible using maximum depositional ages indicated by detrital zircons.
