Limb: It is on either side of the fold. Crest: It is the highest part of the folded bed. Trough: It is the lowest part of the folded bed. Crest plane: It is the line that connects all ... WebFaulting is a complex process and the variety of faults that exists is large. We will consider a simplified but general fault classification based on the geometry of faulting, which we describe by specifying three angular measurements: dip, strike, and slip. ...
