A series of related techniques for determining the age at which a geomorphic surface was created (exposure dating), or at which formerly surficial materials were buried (burial dating). [10] Exposure dating uses the concentration of exotic nuclides (e.g. 10 Be, 26 Al, 36 Cl) produced by cosmic rays interacting with Earth materials as a proxy ...
Surface exposure dating using the isotope 36 Cl was the primary means of dating boulders and terminal moraines in the Drangajökull area in Iceland. [3] Ages of erratic boulders found near the Leirufjörður valley and moraine range from 7-12 thousand years old. [3]
Four decimal places is usually sufficient for most locations, although for some sites, for example surface exposure dating, five or even six decimal places should be used. The [dLL] format can be used within publications to specify points or features of interest and within remote sensing to identify ground truth locations within Digital Earth ...

These younger ages are indications for impact events on the parent body. The cosmic ray exposure (CRE) age of Ribbeck is 55-62 Million years. CRE dating is a technique to determine how long a sample was exposed to space (see surface exposure dating). [5]
