Tektites have been the subject of intense scientific scrutiny throughout much of the 20th century owing to their unknown and possibly extraterrestrial origins, but they are now recognized as having formed from the melting and rapid cooling of terrestrial rocks that have been vaporized by the high-energy impacts of large meteorites, comets, or asteroids upon the surface of the Earth.  4, record 2, English, - tektite

Le choc violent d'une météorite, sur la Terre ou sur d'autres astres, brise les roches préexistantes. Les débris forment une «impactite»; ils sont souvent anguleux. Mais quelquefois la chaleur dégagée par le choc est suffisante pour faire fondre leur bords et même pour provoquer la fonte totale, aboutissant à un verre, ou encore la formation de nouveaux minéraux.  2, record 7, French, - impactite
