However, F, folds are not seen in the area, but indirect evidences in the form of a strong lineation (L,) refolded by later folds are quite common. The So and S, planar surfaces are involved in the 2nd deformation (D2) to give rise to a ...

Older veins are folded or sheared. Younger quartz veins, pegmatites and aplites are associated with the emplacement of Vellingiri granite. The structure is highly complex due to polyphase deformation apart from intense shearing and ...
