Migmatites, Melting, and Metamorphism
Eos, Transactions American Geophysical Union, 1985 This is a praiseworthy collection of papers that illustrates the great range of interests necessary to understand migmatite genesis. The strength of the collection lies in its broad approach to the study of migmatites and its emphasis on the link between “igneous” and “metamorphic” processes.

Numerical Experiment of Rising of Ultramafic and Mafic Rocks by Squeezing
Antarctic Record, 1980 Two mechanisms for the rising of plutonic rocks in terms of their origins are plausible. One is the rising resulted from the buoyancy of acid plutons, e. g. granite and migmatite which are lighter in density, being 2.67 and 2.76 respectively.
