Strewn field

The term strewnfield indicates the area where meteorites from a single fall are dispersed. It is also often used with tektites produced by large meteorite impact.

There are two strewnfield formation mechanisms:

In the case of mid-air fragmentation, smaller fragments tend to fall shorter. That is why the biggest fragment is usually found at one 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.
