Abstract
The metamorphic rocks occurring around Nibhor, northwestern part of the Alwar district, Rajasthan, bear evidence of three phases of folding and one period of regional metamorphism of green-schist facies. The first deformation phase, F1 produced the principal, foliation S1 and the later deformation phases, F2 and F3, produced crenulation cleavages, S2 and S3 respectively. Kinking by the rotation mechanism emerges as the dominant structure supported by kinks with tabular dilatant zones between parted laminae. Some kinks may also have developed by simple shear mechanism.
