Mesoproterozoic
1000 - 1600 Ma
Border Gneiss

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).

Comments: Blue Ridge Basement Complex, Middle Proterozoic (Early or Pre-Grenville-Age) Gneisses

Lithology: Major:{gneiss}
