• The statically recrystallized quartz grains, formed by the heating of the intrusion, show several characteristic microstructures associated with the grain boundary migration. Most of the new grains were formed by the strain-induced migration (bulging) of the original grain boundaries. The new grains contain much fewer fluid inclusions than the old ones, and the boundaries of the new grains contain fluid inclusion arrays. Thus the migrating boundaries result in a change in distribution of the inclusions, may make the picture even more complicated, such as “left over grains” and a cloud of fluid inclusions.
