WebTektites. A Tektite is a rare natural glass formed when an asteroid strikes the Earth. Tektites can be found at at least five widely separated locations on the Earth. Not everything about how the glass forms is fully understood adding to the charm and mystery of this rare material. And for clarification, a tektite is not a meteorite. WebThere is a particular size range wherein spherical tektites re-entering the atmosphere melt on the frontal surface, and the viscous liquid streams back and curls into the pressure eddy at the shoulders, forming the distinctive flying-saucer rims. Rarely, these rims survive impact. A small fraction of this small fraction (of the small fraction ...
