Wikipedia definition

1. Surface exposure datingSurface exposure dating is a collection of geochronological techniques for estimating the length of time that a rock has been exposed at or near Earth's surface. Surface exposure dating is used to date glacial advances and retreats, erosion history, lava flows, meteorite impacts, rock slides, fault scarps, and other geological events. It is most useful for rocks which have been exposed for between 10 and 30,000,000 years.
