Growth faults are syn-depositional or syn-sedimentary extensional faults that initiate and evolve at the margins of continental plates. They extend parallel to passive margins that have high sediment supply. Their fault plane [[dip]]s mostly toward the basin and has long-term continuous displacement. [[:File:Fig_1_Emad_final_thin_boundary1.jpg|Figure 1]] shows a growth fault with a concave upward fault plane that has high updip angle and flattened at its base into zone of detachment. This angle is continuously changing from nearly vertical in the up dip area to nearly horizontal in the down dip area.

Growth faults maturation is a long term process that takes millions of years with slip rate ranges between 0.2-1.2 millimeters per year. It starts when sedimentary sequences are deposited on top of each other above a thick [[evaporite]] layer ([[:File:Fig 1 Emad final thin boundary2.jpg|Figure 2]]). A growth fault is initiated when the evaporite layer can no longer support the overlying sequences. The thicker and denser portion applies much more pressure on the evaporite layer than the thin portion. As a result, a flow within the evaporite layer is initiated from high pressure areas toward low pressure areas causing growth ridges to form below the thin portion. Also, sinking zones are noticed among these ridges at areas where thicker and denser layers form ([[:File:Fig 1 Emad final thin boundary2.jpg|Figure 2]]).
