A relationship between crustal thickness and mean crustal velocity

Variable parameters of the continental crust are: crustal age, heat flow, reflectivity, thickness and velocity. While heat flow and reflectivity decrease, crustal thickness increases with age. For stable crustal regions we present a correlation between crustal thickness and mean crustal velocity. The evaluation is based on more than 270 data points. It is shown that mean crustal velocity is higher in thicker crusts. An attempt is made to relate this observation to crustal growth by accretion from below.
