The Bird River Sill is an approximately 20 km long, east-striking, mafic-ultramafic complex of Archean age (2745 ± Ma) intrusive into the supracrustal Lamprey Falls and Bernic Lake formations of the Rice Lake Group. Subsequent granitic intrusions associated with deformation and complex faulting segmented the originally contiguous sill into offsets that, in places measure more than 1.5 km and have obliterated and/or duplicated parts of the sill.
