The Manereuille Complex was defined by Girard (1995) to describe an informal package of rocks of various composition spatially grouped along the eastern boundary of the Déborah Lake area (sheet 23P05). This sequence of interstratified rocks included metasedimentary rocks, amphibolites, and ultramafic and mafic intrusions. An unpublished regional compilation by the Ministère’s geologists in 2003 formalized the use of the term “Manereuille Complex” and subdivided it into 13 separate units (pPman1 to pPman13). As part of the Southeastern Churchill Province (SECP) synthesis, Lafrance et al. (2018) identified new lithotectonic domains within the SECP and moved the boundary between the Rachel-Laporte and Baleine lithotectonic domains to the west.


Reasons for Abandon

Following displacement of the boundary between the Rachel-Laporte and Baleine domains to the east, rocks of the Manereuille Complex were reassigned to units of the Baleine Lithotectonic Domain. The Manereuille Complex consisted of numerous units of various origins. Field checks conducted as part of the SECP synthesis allowed for a new interpretation of these units and their reassignment to appropriate units. Depending on rock type, units of the Manereuille Complex were reassigned to the following units: 1) amphibolites of the Curot Suite (ApPcut), 2) metasedimentary rocks of the Akiasirviup Suite (ApPaki) and 3) mafic and ultramafic intrusive rocks of the Ralleau Suite (ApPral).
