Description :
Fig. 12A. Three Lakes formation at station 10JP166 along its type transect on the west side of Showing lake ("S" near the centre of Fig. 8). Wavy transposed layering in fine and coarse phyllitic siltstone is parallel to SP1b foliation and the axial planes of isoclines (FP1 arrows) with truncated limbs. Dark spots are chlorite-altered MP2 biotite porphyroblasts (Knox, 1980). Interpreted as ripple laminae initially.
