The regional foliation of these lithounits is NWSE with low to moderate southwesterly dip. Bedding (S.) is the most important planar surface represented by colour and compositional banding within the metasedimentary lithounits.

The veins parallel to the shear foliation are syntectonic while those cutting across the shear foliation are mostly extension gash fillings and are syn to late tectonic. Older veins are folded or sheared.

The foliation trend is N35° to 40°E to S35° to 40°W with vertical dip. Two sets of prominent joints were observed — 1) N60°W to S60°E dip vertical and 2) N50°E to S50°W dip vertical. Seepage in the masonry body in the form of oozing was ...
