John Wakabayashi's 2007 paper explores what
happens to sedimentary deposits along a strike slip fault with
releasing and restraining bends. A releasing bend may open a basin
along a fault in a sag pond or pull-apart. A restraining bend may create
an antiformal or thrust-cored ridge, from which sediments are shed. As
fault slip continues, both features will
grow, and the depocenters will migrate along the fault. You can see
what this looks like on a geologic map from two of his several examples:
the Merced Formation (marine sediment)
lying between two strands of the San Andreas in an extensional basin and
Mt. Diablo, an uplifted anticlinorium
between two other strands across the San Francisco Bay.
Sarah Titus made maps of folds along the San Andreas Fault in central California, where the fault is currently creeping at nearly the whole plate rate, and folds are currently tightening and uplifting the surrounding landscape. By comparing the folds to experimentally deformed sheets of clay, she was able to determine the compression angle across the fault which caused/ is causing the uplift of the surrounding hills.
ten Brink and Ben-Avraham defined the three dimensional evolution of the pull-apart basin known as the Dead Sea rift. Seismic lines perpendicular to the rift axis show faults that branch toward the surface and have complex apparent offset patterns. Throw varies along strike. The simplified model shows the linking up of a series of pull apart basins, each bounded by its own small border fault system.
