Folds in multilayered rocks of Proterozoic age, Rajasthan, India
A M Bhola B K Sharma S K Ghosh
First phase folds F1 developed in polydeformed Ajabgarh Group rocks of Proterozoic age are studied using various geometrical methods of analysis for compatibility of homogeneous strain in both class 1–3 pairs by correlating
F1 folds were initiated by the process of buckling but underwent [(λ2/λ1) = 0.2 to 0.7] for competent layers and

Kink bands in thrust regime: Examples from Srinagar—Garhwal area, Uttarakhand, India
Shashank Shekhar A M Bhola P S Saklani
This paper deciphers the late stress systems involved in the development of kink bands in the perspective of thrust regime. In kink bands, the correlation coefficient for 𝛼-𝛽 plots is positive near thrusts and negative away from thrusts. The plots show nearly linear relationship near thrusts and non-linear relationship away from thrusts. The rotation was prominent mechanism of kink band formation near thrusts and rotation coupled with shearing, along the kink planes away from thrusts. Along thrusts 𝜎1 is horizontal E–W trend and it rotates to horizontal N–S trend away from the thrust. The proposed model establishes that (1) the shearing along kink planes led to angular relationship, 𝛽 > 𝛼 and (2) the kink planes of conjugate kinks could be used for paleostress analysis even in those cases where shearing along these planes has occurred.
