Tektites are nearly pure glasses (practically no crystalline inclusions) created when a space rock slams into Earth, melting surface material and hurling it hundreds or even thousands of km. “Tektites are a specific type of impact-produced glass, defined in particular by their occurrence within large strewn fields lying at long distances from their source crater,” said Curtin University’s Professor Fred Jourdan and his colleagues. “Finding a new tektite field is like opening a fresh chapter in Earth’s violent geological past,” Professor Jourdan said.
