Sr isotope data on 15 samples indicate that the boundary zone may be explained by interaction between chemically distinct melts. The granitic melt was derived from a source richer in radiogenic Sr than the granodiorite melt, and the granite in the interior of the pluton underwent crystal fractionation. The apparently simple zoned Criffell pluton is actually a composite of unzoned and zoned components, and the boundary between components is of a transitional character of variable chemical gradient.
