Gold mineralization distributed on the periphery of the Opinaca Subprovince may be associated with decollement structures of such a complex. Much of the Opinaca Subprovince has been covered by geological surveys at this scale or lower. It is located 140 km east of James Bay, south of the Robert-Bourassa Reservoir and south of Lac Sakami. These intrusions are peraluminous and type S (Moukhsil et al., 2003). Grey Bruce Wildflowers Stone Age Skills   Ministère des Ressources naturelles, Québec; RG 2001-15, 55 pages, 3 plans. In the Guillaumat and Sakami lakes area (sheets 33F02 and 33F07), the boundary between the two subprovinces is a NE-oriented thrust fault that separates volcanic rocks of the Yasinski Group and metasedimentary rocks of the Laguiche Complex (Goutier et al., 2000). AUGLAND, L.E. This age range would also correspond to the deposition age of two sedimentary basins in the La Grande Subprovince, dated <2686 ±3 Ma and <2714 Ma (Ravenelle et al., 2008, 2010), north of the Opinaca Reservoir. Construction of a steel-wood bridge that crosses the Opinaca River. According to Hocq (1994), the boundary between the Opinaca and La Grande subprovinces generally corresponds to regional deformation zones cut by tonalitic and granodioritic intrusions. just west of, and almost under, the bridge. These rocks contain 20 to 50% tonalitic or granitic mobilisate and are characterized by well-developed migmatitic banding (Bandyayera and Fliszar, 2008). There currently are no relevant websites listed. To date, geological knowledge remains incomplete in a portion of its central section and in contact with the Opatica Subprovince west of the Otish Basin. dios k2 directly bordering azimut elmer in opinaca river trend.

Metasedimentary rocks of the Opinaca are intruded by multiple post-tectonic to late-tectonic intrusions consisting of granodiorite, pegmatitic granite and tonalite cutting paragneiss of the Laguiche Complex. Simard and Gosselin (1999) place the boundary between metavolcanic rocks of the La Grande Subprovince and metasedimentary rocks (Laguiche Complex) of the Opinaca Subprovince.

Supracrustal rocks belonging to the Hublet Group (Mercator Formation) consist of early gneiss that are likely derived from grauwacke and that contain volcanic rocks (Lamothe et al., 1998). River from under the bridge. The piers are in steel and sit on piles. Mobilisate injections would preferentially be aligned with domes and the centre of basins would be occupied by late intrusions. In general, the Opinaca Subprovince is characterized by increasing metamorphism towards the south from its contact with the La Grande Subprovince. Rapport du CONSOREM 2007-07, 36 pages. – BEGIN, N.J. However, their relationship with metasedimentary rocks of the Laguiche Complex is unknown. The Opinaca Subprovince corresonds to the remains of a large sedimentary basin. Construction of a steel-wood bridge that crosses the Opinaca River. The piers are in steel and sit on piles. In its tectonometamorphic interpretation of the northern Superior Province, Cadéron (2003) established the first geothermobarometric data characterizing metasedimentary rocks of the Opinaca Subprovince. – SHARMA, K.N.M. Metasedimentary rocks of the Laguiche Complex mainly consist of paragneiss, metatexite and diatexite. Lightning caused a forest fire here in 1989.

RAVENELLE, J.-F. – DUBÉ, B. This website is created, maintained & copyright © by In the Opinaca Reservoir area, rocks of the Opinaca Subprovince show a deformation pattern in domes and basins; the core of the domes is occupied by late granitic intrusions (Bandyayera et al., 2010). The magnetic signature of the Opinaca Subprovince is relatively weak and punctuated by intense linear anomalies, many of which correspond to strips of metavolcanic rocks and iron formations (Sharma, 1978; Chartrand and Gauthier, 1995; Gauthier, 1996). The work of Doyon (2004) also suggests that the Quetico, Nemiscau and Opinaca basins are geochemically similar. Metasedimentary rocks of the Opinaca Subprovince would therefore come from erosion of the La Grande and Opatica subprovinces.
