The oldest plutonic rocks in the Central plutonic belt are foliated granites that generally yield Floian to Darriwilian (Early to Middle Ordovician) U-Pb (zircon) ages (Whalen 1993; Whalen et al.

The ultramafic rocks are confined to a thrust slice of the Annieopsquotch ophiolite belt that is bounded by the northwestern shear zone of the Lloyds River Fault Zone, and is separated from the main ophiolitic bodies by plutonic rocks that intruded the Lloyds River Fault Zone syn-kinematically (Fig.
