Evidences of Multiple Deformations Near Amaidegri in the Western Part of the Gangpur Group

Three phases of folding have been detected in a large exposure along the Sapai lladi near Amaidegri (22°01': 84°08') in the Ghoriajhor manganese belt in the western part of the Gangpur Group. Reclined to inclined folds (F₁) plunging SSE have been coaxially refolded by open upright F₂ folds, and finally, upright folds with ENE-trending axial planes (F₃) cause culmination and depression of axes of open-folded reclined folds. The multiple deformations cause characteristic outcrop patterns and they are reflected in two distinct S-pole girdles around a plane of symmetry which is the axial trend of F₃ folds.
