What is Meteorite strewnfield?
[[File:Pultusk meteorite strewnfield.png|thumb|Example of meteorite strewnfield: distribution ellipse of [[Pultusk (meteorite)|Pultusk meteorite]]]] A '''meteorite strewnfield''' is the area where [[meteorite]]s and glassy [[tektite]]s from a single meteor fall are found.<ref>{{cite book| last1 = Faure| first1 = Gunter| last2 = Mensing| first2 = Teresa M.| title = Introduction to Planetary Science: the geological perspective| url = https://books.google.com/books?id=U4FZp6f6q6MC&pg=PA118| year = 2007| publisher = Springer Science & Business Media| isbn = 978-1-4020-5544-7| page = 118 }}</ref><ref>{{cite book| author = Gerald Joseph Home McCall| title = Tektites in the geological record: showers of glass from the sky| url = https://books.google.com/books?id=1mywn15XjFIC&pg=PA10| year = 2001| publisher = Geological Society of London| isbn = 978-1-86239-085-0| page = 10 }}</ref><ref>French, Bevan M 1998.

When a large [[meteor]] enters the [[atmosphere]] it often fragments into many pieces. This showers the material over a large oval-shaped area. The shape of this oval is caused by the flight path of the meteor. When multiple-explosions occur, the material may be found in several overlapping ovals. # Impact fragmentation: the fragmentation can occur on impact. In this case the strewnfield shape may be different, usually circular. == Example == * The [[Australasian strewnfield]] is the youngest and largest of the tektite strewnfields. Recent estimates suggest it may cover 10%-30% of the [[Earth]]'s surface.<ref>Povenmire H; Liu W. & Xianlin I. 1999.
