crater density studies (crater counting) The establishment of the relative age of a portion of a planetary or satellite surface from the observed density of meteorite impact craters. If a calibration is available for the meteoric flux (e.g. from dated lunar surfaces), absolute ages may be obtained by this technique. Problems with the method include the identification of primary from secondary craters, and whether the surface is saturated with craters.
