Belt: Abitibi
Tectonic Assemblage: Timiskaming
Geological Age: Archean
Jun 04, 2010 (D Guidon) - From Alexander 2007 The Upper Canada property is primarily underlain by Timiskaming assemblage flows, tuffs and sediments with syntectonic dykes, sills and plugs of syenite . The Cadillac-Larder Lake Break, which separates the Timiskaming and Tisdale assemblages in this area, is further south on the Anoki-McBean claims. Upper Tisdale assemblage felsic tuffs and volcanic breccias, however, are noted in the far eastern limits of the property near Little Larder Lake. This area is east and north of the north margin of the younger Timiskaming assemblage basin - contact disconformable and locally faulted. Formerly called the Gauthier Group, the felsic volcanics are designated Upper Tisdale assemblage from recent geochronology by Ayer et al (2001, 2002 and 2005).
