Scope of Project:
The Geraldton-Onaman transect is a 105 km long traverse that crosses a major terrane boundary between the eastern Wabigoon and the Quetico subprovinces in the western Superior Province. It is considered to be one of the poorly metal-endowed transects because despite the numerous precious and base metal occurrences, significant mineral deposits have yet to be discovered in the area. The only significant gold mineralization is indicated by several small past-producing and future gold mines in the Beardmore-Geraldton belt that stretches along the boundary between the eastern Wabigoon and Quetico subprovinces with ca. 10 Moz Au total mined-out and existing reserves/resources (Mason and White, 1986; G Mining Services, 2016).
The transect area has a complex and poorly understood geological evolution. The research area is made up of several Mesoarchean and Neoarchean mafic to felsic volcanic assemblages (~2970 Ma to 2720 Ma) overlain by fine to coarse-grained clastic and chemical sedimentary successions (~2710 Ma to 2690 Ma) and large granitoid plutonic bodies (~2920 Ma to 2650 Ma; Stott et al., 2002).
The transect research aims to improve our understanding of the geological evolution of the transect area using geological mapping, whole rock and isotope geochemistry, geochronology, structural analyses and various geophysical methods that provide an insight into the 3D lithospheric architecture. The outstanding questions include the petrographic and petrologic characterization of the various metavolcanic, metasedimentary and intrusive rocks, the characterization of various metallogenic processes, as well as deformation and metamorphic events.
