Thank you sir... I think you are the best structural geologist in india.. explanation is very easily understandable.. thanks alot

[@Matthughes1100]

It would be great if it had a class about extensional and strike-slip regimes and features

[@abhisheksingh2588]

Sir, the propagation direction is same in both the illustrations used for fault bend fold and fault propagation fold at 42:02 and 44:15 respectively, the point i did not get is how are we naming the backlimb and forelimb in both the cases. I thought it is propagation direction but then it should be same in both the cases. what is the criteria Sir??

[@santanumisra3267]

You are right. At 42:02 (fault bend fold), the labels of the illustration are wrongly placed, the should replace each other. At 44:15 (fault propagation fold), the labels are wrong in the last image. Thank you for pointing this out. I'll correct it in the next version.

Thank you sir

Sir, at 47:21 the drawn fault propagation fold looks very similar to thrust nappe. How to distinguish between these two in the field?
