1000 - 1600 Ma
Age: Mesoproterozoic (1000 - 1600 Ma)
Stratigraphic Name: Border Gneiss
Description: Border gneiss (Hillhouse, 1960). Pyroxene- and locally graphite-, sulfide-, and garnet-bearing quartzofeldspathic granulite and gneiss; includes platy leucocratic charnockite and charnockite gneiss; surrounds and is intruded by Roseland Anorthosite. Border gneiss is equivalent to banded granulite of Herz and Force (1987), and has been interpreted as in part a paragneiss derived from pre-Grenville-age sedimentary-volcanic rocks (Bartholomew and Lewis, 1984; Herz and Force, 1987).
