Cosmogenic 3He surface-exposure dating of stone pavements

The surface exposure dating is being correlated with the ages from the lake sediment cores, applying a second independent method of dating Greenland’s ice sheet extent. Additionally, the dating expands the overall area of dating coverage as it provides a method that can be used to connect between the areas where lake sampling is possible.

Cosmogenic exposure dating, also known as surface exposure dating, is used to estimate the amount of time a rock has been exposed at the surface. It is useful for dating many different geological events such as, fault scarps (which is a displacement of the surface of the land because of fault movement), rock slides, meteorite collisions, lava
