Chevron (land form)

From Wikipedia, the free encyclopedia

See also: chevron (disambiguation)

A chevron is a wedge-shaped sediment deposit observed on coastlines around the world. These formations sometimes include tiny fossils from the ocean.

Such formations are generally hypothesised to be created from erosion, glaciers, and other natural phenomena.

The Holocene Impact Research Group hypothesizes that the formations could be caused by tsunamis from meteorite impacts or submarine slides which lift sediment up and carry it hundreds of miles until depositing it on coastlines. This idea is controversial because chevrons are similar to wind-blown landforms found far from the ocean, and because it is unlikely that there have been enough large impacts and landslides to explain the observed chevrons.

Many chevrons can be found in Australia, but others are concentrated around the coastlines of the world. For instance there are chevrons in Hither Hills State Park on Long Island and in Madagascar.
