Description :
Fig. 10B. Sericite schist partings in pale green vitreous quartzite (parallel to felt pen) define transposed bedding (S0=SP1) and range from stylolitic to structurally lineated and shingled in the R22 area (Fig. 8). Apparently opposing festoon crossbeds are highlighted in cross section by late hematite alteration but not visible on the sheared S0=SP1 surfaces. Pink hematite at bottom is a late thin coating along a joint plane.
