As a result of melt overpressure, the feldsparaggregate dilates and the melt is accumulated in intergranularand intragranular pockets and fractures.[56] It is likely that the evolution in the orientation of meltpockets is caused by the increasing melt fraction and/or bythe change in differential stress magnitude and orientation[Cosgrove, 1997]. The implication of the increasing meltfraction and connectivity certainly influences the distributionof local compressive and shear stress magnitudesand orientations and the active deformation mechanism(Figure 16). In this context, it is not likely that the meltpreferred orientation is controlled by the variations indifferential stress [Gleason et al., 1999], hydrostatic annealing[Daines and Kohlstedt, 1997] or variations in thewetting angle [Walte et al., 2005]. In order to further explainthis relationship between melt seam orientations and meltfractions more analogs and possibly numerical modeling isneeded.[57] In Type II microstructures the diffusion creep ratesof both feldspars were effectively enhanced by the interstitialmelt phase wetting their boundaries and leading to arapid strength drop within the MCT field as proposed by[Rosenberg and Handy, 2005]. This is consistent with a lowamount of melt
