The George Complex, defined as an informal package of gneiss of uncertain protolith by van der Leeden (1994, 1995), consisted of a package of highly deformed rocks that included orthogneiss, intrusions and metavolcanics. Previous work by the Ministère formalized the use of the George Complex and divided it into several informal units (MRNF, 2010; Lafrance et al., 2014). The unit was abandoned by Charette et al. (2018) following field checks in the summer of 2016 as part of the Southeastern Churchill Province (SECP) regional synthesis (Lafrance et al., 2018).
Units of the George Complex were divided into two distinct lithotectonic domains and located on either side of the Rivière George Deformation Corridor: the George domain to the west and the Mistinibi-Raude domain to the east. It included many units of various and poorly defined origins. Field checks conducted as part of the SECP synthesis allowed for a new interpretation of these units and their reassignment to better constrained units. Depending on the rock type and location, George Complex units were reassigned to: 1) orthogneiss and intrusions of the Advance Complex (ApPadv); 2) intrusions of the Déat Suite (pPdea); and 3) metavolcanics, metavolcaniclastics, paragneiss and synvolcanic intrusions of the Tunulic Complex (nAtun).
