We propose a method to estimate probability of crustal thinning during exhumation of a metamorphic complex. We firstly assume that the maximum horizontal displacement was same as the vertical distance, ΔD. The probability of thinning is expressed as a function ofΔD/L. We secondly treat the maximum horizontal displacement as a variable x to express the probability as a function ofΔD/L and x/L. The probability at constant ΔD/L decreases when x/L approaches ΔD/L. The former evaluation provides approximately minimum estimation of the probability of the crustal thinning.
