Abstract:
      An estimation of burial depth of Alborz rock units is carried out in order to recognize the exhumed regions of the orogen, on the basis of the geological map of Iran on 1:1000,000 scale.studying the burial depth distribution laid over the fault map indicates that the contour gradients strongly increase along the major fault zones, which shows that the faulting has caused an increase in exhumation rate in the Alborz range. The mean elevation of the range is calculated and was applied to the related empirical relationship, by which the mean denudation rate of the Alborz range was estimated to about 0.467 mm/yr.
