Abstract:
In the northern Baltic Shield, diorites, monzodiorites, and quartz diorites are constituents of postorogenic granite massifs, the localization of which was controlled by NE- and NW-trending fault zones. The NE-trending transform faults controlled the emplacement of the Litsa–Aragub and Yuovvoaiv complexes (1.77–1.76 and 1.79–1.77 Ga old, respectively); the Vainospäa Massif; and, probably, the “Nattanen-type” massifs (Nattanen, Tepasto, Pomovaara, Riestovaara) (1.8 to 1.77 Ga old [3]) located at the southern framing of the Lapland granulite belt.
