Quick Summary

A strewn field is an area where tektites are found. Tektites are natural glassy objects formed from terrestrial rocks melted by high-energy meteorite, comet, or asteroid impacts. These impacts create clouds of molten rock that cool rapidly into glass before falling back to Earth. Tektites are found in specific locations called strewn fields, which are associated with impact craters. Examples include the Australasian strewn-field, dating back about 800,000 years, and the Czech Republic's moldavite strewn-field, formed around 14.6 million years ago.12

…which the meteorites fall, the strewn-field, is generally a rough ellipse along the direction of flight. Because air resistance slows down larger fragments less quickly than smaller ones, the larger fragments travel farther, giving a size gradation along the direction of flight.

The North American strewn-field, dated at 35.4 million years ago, has yielded a few tens of thousands of tektites, mostly splash-form in type.
