Summary

In oblique-slip fault-zones strike-slip movement on a rising block carries a sequence of source rocks past a locus of accumulating sediment on the adjacent, stationary, sinking block. A diachronous stratigraphy of sediment from distinctive source rocks may result, getting younger in the direction of strike-slip motion on the rising block. Four models of sedimentation in non-marine and shallow-marine environments are presented, and illustrated by New Zealand examples. Interpretation of oblique-slip faulting in ancient non-marine sediments requires recognition of (a) clasts from distinctive sources, (b) diachroneity of earliest and/or latest appearance of clasts, and (c) palaeo-flow direction. In zones of known oblique-slip, knowledge of one or two of those three factors would allow prediction of the others.
