James H. Wittke, James C. Weaver, Ted E. Bunch et al., 2013. Proceedings of the National Academy of Sciences 110(23).

About 700 SEM-EDS analyses of spherules from 18 sites in North America, Europe and the Middle East; argues they formed by melting of sediment above 2,200 °C and estimates 10 million tonnes spread over about 50 million km².
