Do you mean density in the crystallized state, or partially molten? As a guide, the density of granite is about 2.7 g/cc, and granitic melt is about 0.4 g/cc less, so you can estimate the overall density from the fractions of the solid and liquid components. A more sophisticated estimate will take fully into account the mineralogy, total pressure, temperature and water pressure effects.

Subject: Density Ranges of Migmatites
Hi all,
While developing an analytical model on extrusion of the Higher
Himalaya, I was looking for the density range for migmatites. I
searched a lot in various textbooks, papers and handbooks but couldn't
get any. Could you let me know the range along with full references?
Thank you in advance!
Sincerely,
Dr. Soumyajit Mukherjee
