... in Quebec. Immediately north of the LLCDZ along this segment, deformation of the less than ca. 2687 Ma metasedimentary Cadillac Group began with the formation of isoclinal F 1 folds, which are overprinted by post-2676 ± 2.0 Ma regional F 2 folds with an axial planar S 2 cleavage oriented parallel...

(A) Geological map of the Cadillac Group. The latter is folded by regional isoclinal F2 folds overprinted by Z-shaped F3 folds. The Piché Group is also folded by an F2 fold. The location of the section in (B), the outcrop maps of Fig. 7, and the detailed map area in Fig. 13 are represented by the black A–A′ line, the red outcrop outlines, and the black open rectangle, respectively. Distribution of lithological units is from Gunning and Ambrose (1940), Pilote (2013), and mapping by authors.
