Folded australite bowl from Port Campbell district, Victoria, Australia

A folded australite (tektite) from Goudie's Lookout, Victoria, was a thin oval or boat- shaped bowl of approximate dimensions 17 x 8 x 4 mm. It developed from a small, elongated primary body by aerodynamic processes during passage at hypersonic speeds through the earth's atmosphere, but while still hot and plastic, the sides folded backward and were fused together. Peculiarities of shape arose from the excessive length of hinge relative to the perimeter of the bowl. No impact damage resulted at the earth's surface but subsequent terrestrial weathering effects are evident.
