Previously, two layers containing impact melt spherules, the Wittenoom spherule layer and the Carawine spherule layer, exposed in the main outcrop area and Oakover River area, respectively, of the Neoarchaean – Palaeoproterozoic Hamersley Basin of Western Australia, were correlated. Subsequent discovery and study of the Jeerinah spherule layer in the main outcrop area, as well as a new Carawine spherule layer exposure now suggest that the Carawine and Jeerinah spherule layers are correlates. The previous Wittenoom – Carawine correlation was based on the presence of spherules and sedimentological consistency: both layers comprise sediment gravity flows, and the Wittenoom spherule layer was interpreted as the downflow equivalent of the Carawi...
