Pic of the day #22 (fault termination)

Pic Source: Earth Structure – An introduction to structural geology and Tectonics

(a) Cross-sectional sketch showing various types of fault terminations. The fault terminates at the ground surface at point A; at point B, the fault has been cut by a pluton; at C and D, one fault cuts another; at E, the fault was eroded at an unconformity.
(b) Termination of a fault by merging with another fault (at point A), or by horsetailing (at point B) and dying outinto a zone of ductile deformation (at point C).
(c) A series of ramps merging at depth with a basal detachment.
