AbstractThe Bee Lake greenstone belt consists of a relatively simple volcano-sedimentary stratigraphic sequence that has undergone two folding events and subsequent brittle-ductile faulting. These rocks have been intruded by several generations of dykes and plutons that, once dated, will allow the timing of deformation to be constrained. The supracrustal sequence consists of basal massive basaltic flows, pillow basalt, and pillow breccia, which are overlain by felsic volcaniclastic and epiclastic tuff and breccia that are locally interbedded with arkosic or quartzose wacke and conglomerate. Locally the conglomerate contains boulder-sized clasts of granodiorite that has under- gone little to no pre-entrainment deformation. Previously the Bee Lake greenstone belt has been correlated with the Confederation assemblage. However, the noticeably different rock types and stratigraphy between this region and the type section for the Confederation assemblage suggest that this correlation is invalid.
