you can use these types of tectonics in soft and hard rocks. There are many examples of them in loess, e.g., Hungary and several in crystalline (hard) rocks as well.
I can give you one example from the Dead Sea Transform Fault below:
DILL, H.G., HAHNE, K. and SHAQOUR, F. (2012) Anatomy of landslides along the Dead-Sea-Transform Fault System in NW Jordan.- Geomorphology, 141-142: 134-149.
Thank you Dear Prof Herald. I shall be happy if you kindly send me the soft copy of that paper. Also suggest me that same parameters can be applicable both in soft and hard rocks in tectonic study because my study area covers both rocks.
