Abstract

Structural mapping in this area in Bankura district of West Bengal reveals coaxial easterlyl westerly plunging early isoclinal F₁ folds and later upright F₂ folds giving rise to hook-shaped interference patterns. Later slip and shearing along the F₂ axial plane cause considerable bending of early linear structures in both mesoscopic and macroscopic scales. All rock types including anorthosite, granite gneiss and composite gneiss are affected by multiple deformation plan.
