Strewn field

A strewn field is the area where meteorites from a single fall are dispersed.

[1] It is also often used for the area containing tektites produced by large meteorite impact.

[2] There are two strewnfield formation mechanisms: In the case of mid-air fragmentation, smaller fragments tend to fall shorter and the biggest fragments are usually found at the far end of the oval.

In order to get an idea of the original flight direction it is necessary to analyze the size pattern of the material over the strewnfield.

Fragments of about 1 to 5 grams can be picked up on weather radar as they fall at terminal velocity.
