Description:
Oblique motion along tectonic boundaries is commonly partitioned into slip
on faults with different senses of motion. The origin of slip partitioning is important
to structural geology, tectonophysics, and earthquake mechanics. Partitioning can be
explained by the upward elastoplastic propagation of oblique slip from a fault or shear
zone at depth. The strain field ahead of the propagating fault separates into zones of
predominantly normal, reverse, and strike-slip faulting. The model successfully predicts
the distribution of fault types along parts of the San Andreas and Haiyuan faults.
