The Hutte Sauvage Group is an epicontinental siliciclastic sedimentary sequence deposited onto polycyclic gneiss of the Rae Province, between the New-Québec (Labrador trough) and Torngat Lower Proterozoic orogens. Bounded to the west by the George River shear zone, the Hutte Sauvage Group shows an asymmetric facies distribution. From west to east, and from base to top, it is made of talus conglomerate, alluvial fan arkose, and wacke–quartzite assemblage of probable fluvial origin. The talus conglomerate includes fragments from lithodemic units to the west, indicative of a local derivation. Boulders from the De Pas Batholith imply a maximum age of 1.84 Ga for the onset of sedimentation. Structural analysis of the basement faults, along with the sedimentary facies analysis, suggest erosion and sedimentation along a fault scarp affected by normal scissors-like movement coinciding with the George River shear zone. The Hutte Sauvage Group deposition being younger than the regional transcurrent shearing and the arc magmatism episode, the group is therefore considered to be the youngest supracrustal assemblage preserved in the New-Québec and Torngat orogens.
