— The toroidal (doughnut) form of tektite is one of the possible primary forms that could be developed by a spinning globule of molten glass in null gravity. A description is given of a tektite specimen found in the Lake Torrens Region of South Australia. It could have developed from a toroidal primary form, although another way of producing the shape from a core with a deep bubble pit is also suggested.
