description Glikson Overview
Glikson is an eroded impact structure in the Little Sandy Desert of Western Australia. Geological studies describe a roughly 19 km diameter zone of deformed Neoproterozoic sedimentary rocks, with shatter cones and planar microstructures in quartz supporting an impact origin. Its ring-shaped aeromagnetic anomaly helped reveal the structure, which was named in honor of geologist Andrew Glikson.

help Glikson FAQ
Where is the Glikson impact structure?
Glikson is in the Little Sandy Desert of Western Australia. It is an eroded structure formed in Neoproterozoic sedimentary rocks.
How large is Glikson?
Geological studies describe a deformed zone roughly 19 kilometers in diameter. The measurement describes the broader impact-related structure rather than a sharp modern crater edge.
What evidence shows that Glikson formed by an impact?
Researchers have identified shatter cones and planar microstructures in quartz. These features are important shock indicators because they form under the extreme pressures associated with impacts.
Why is there no obvious crater at Glikson?
Glikson has been heavily eroded and lies in the Little Sandy Desert, so its original crater shape is not preserved at the surface. The impact interpretation comes from the deformed rock zone and shock features.
