The grand mean values of Si-O distances in both the left and the right sides of 33 metamorphic reaction equations have been calculated on the basis of data of single crystal structural refinement analysis. The results showed that the grand mean value of Si-O distances tends to decrease at high temperature, whereas that tends to increase at high pressure during a metamorphic reaction.
