Sr and Nd data for clinopyroxene spherules from three sites (DSDP Site 216 in the Eastern Indian Ocean, ODP Hole 709C in the western Indian Ocean and ODP Hole 1090B in the western South Atlantic) support conclusions that there is only one clinopyroxene spherule layer and that the source crater may be Popigai. Sr and Nd data for microtektites from a site in the Southern Ocean (ODP Hole 689D on Maud Rise) alongwith the data from DSDP Site 216 suggest that they do not belong to the North American strewn field.
