The relatively new technique of surface exposure dating (SED) utilises primarily the build-up of 10 Be in rock materials over time rather than its radiometric decay: Its amount and that of other cosmogenic isotopes (e.g., 26 Al, 21 Ne, 3 He, 36 Cl), produced in-situ within a rock matrix due to exposure of the rock to cosmic rays, contains information about the exposure history.

Surface 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, cave development, and other geological events.

Feb 23,  · 26 Al/ 10 Be Burial Dating of Xujiayao-Houjiayao Site in Nihewan Basin, The Xujiayao-Houjiayao site in Nihewan Basin is among the most important Paleolithic sites in China for having provided a rich collection of hominin and mammalian fossils and lithic artifacts. Burial dating with 26 Al and 10 Be is now a well-established.

Cosmogenic-nuclide burial dating is a means of dating geological deposits by measuring pairs of rare nuclides that are produced at a fixed ratio during cosmic-ray bombardment of a rock or mineral target, but have different half-lives (see Granger, for a complete overview).

Limitations of Burial Dating of Basin Fill and Growth Strata. In this study of alluvial strata in the western Tarim Basin, we successfully used burial dating, in conjunction with magnetostratigraphic dating, to reliably date coarse-grained basin fill using seven samples with ages spanning from ca. Ma to ca.
