- •
Purpose: examine experimentally control of anisotropies on melt flow in migmatites.
- •
Experiments on a homogeneous gneiss and one with strong mineral layering.
- •
Initial anisotropy strongly controls melt flow and segregation at sample-scale.
- •
Initial anisotropy also controls deformation distribution and its partitioning.
- •
Boudinage occurs in the gneiss with mineral layering.
