1958 Geol. Mag. 95 383 The infrastructure, although undergoing migmatization, retains the trends of the older orogenic belt from which it is largely formed.
1971 Sc. Jrnl. Geol. 7 323 The frequent spatial coincidence between areas of migmatization and centres of high-grade regional metamorphism has long been recognized.
1997 Jrnl. Mining & Geol. 33 81 Intrusion of granitic material appears to have contributed to migmatisation in the rock.
