    • 2 becomes more rapid with time (possibly due to the onset of magnetite crystallization) rather than decreasing, as would be expected if crystal-liquid separation was slowed by increasing viscosity.

    • 2 in the Lesser Antilles and Indonesia, suggesting an important role for mixing in those island arcs. With the exception of Martinique in the Lesser Antilles [J. P. Davidson, J. Geophys. Res. 91, 5943 (1986)], these increases are not strongly correlated with long-lived radiogenic isotope tracers of Sr or Nd, further suggesting that the assimilant is often preexisting, unradiogenic arc crust.
