Abstract
A detailed study and analysis of all the planar and linear elements in the lithic units of the area, in both meso and macro scale reveal that they bear the impress of three phases of folding, F
1 F
2 and F
3. The most dominant phase is the second phase resulting in open asymmetric folding with high wave length/amplitude which express in mesoscale crenulations on the planar surface of F
1 folding. The F
1 phase is responsible for the regional foliation S
1 which is parallel to lithic banding S
0. The tight isoclinal folds develop appressed surface which act as form-surface of F
2. The F
1 and F
2 are generally co-axial. The last phase of folding F
3appear as broad open cross-folds broadly warping the pre-existing foliation. This phase can distinctly be observed on map scale.
Distinction between each phase and the associated structures is based on the overprinting relations, in particular the bending of axial surface foliation and other interference patterns between the existing phases. Structural analysis of the area indicates operation of a predominantly sub-horizontal NW-SE oriented stress.
