Conjugate transfer zones must have major normal faults dipping in the opposite direction. This classification can be farther divided into convergent and divergent transfer zones. Convergent transfer zones dip toward each other and in result more complex faulting and folding can occur in the zones between them. Divergent transfer zones dip in opposite direction and often result in topographical highs. Major fault boundaries within rift systems tend to expand with time based on the assumption that the extensional stress and strain is consistent in a given rift system. Transfer zones have been identified according to the fault propagation evolution; they include approaching, overlapping, collateral, and collinear. This classification assists in visualization and deformational history of the transfer zone. When transfer zones are in the approaching stage the major boundary faults have not propagated past one another yet. Transfer zones are in the overlapping stage when the major boundary faults have propagated past one another. This only includes faults that are partially overlapping. Collateral transfer zones include area where faults are completely parallel and overlapping. The geometry is frequently seen in horst and graben structures. Collinear transfer zones include areas which the major fault boundaries are in line with one another. In many cases this geometry relies on the faults to splay at their terminations and interfinger with one another. While the East African rift system is experiencing profound extension the transfer zones that link major extensional faults do not experience this extension. Transfer zones within the East African rift are most commonly in the overlapping stage but every stage has been observed. Here, transfer zones are generally high areas with complex internal fault geometries. These general high areas generally are conjugate divergent type zones and have been observed in the Tanganyika rift and Albertine rift of Uganda. These broad highs can have vast effect of drainage as they can potentially split basins. Synthetic relay ramp style transfer zones are frequently observed in Lake Malawi. Brief examples have been given but all types within the synthetic and conjugate classification have been observed in the East African rift system. Suez rift transfer zones are similar to the East African rift transfer zones in that potentially any classification type and stage can be seen. However a study has shown that the transfer of deformation in transfer zones can be accomplished in two ways; through faults or accommodation zones between two opposite dipping normal faults in a horst and graben. A few kilometers south of Cairo there are en echelon minor faults between two major faults that produce a relay ramp style transfer zone. In the northern part of the Suez rift system the Gharandal transfer zone accommodates deformation in a broad anticlinal structure between two listric faults in a collateral horst and graben.
