Tektites: Origin

Scientific paper

Tektites are generally small, black, rounded, silicate glass bodies found scattered over several widely separated areas of the Earth's surface called strewn fields. The major, trace, and isotopic compositions of tektites indicate that the parent material was a terrestrial sedimentary deposit, and the presence of lechatelierite, coesite and shocked relict inclusions favors an impact origin. Furthermore, two tektite strewn fields have been associated with known impact craters, and tektites from one strewn field have been found associated with impact ejecta.
