Low-angle thrusts in Cenozoic rocks in Canterbury, New Zealand

Abstract

Two examples of low-angle thrusts which lead to repetition of succession have been located, one in the Cenozoic rocks of the Esk Valley outlier in Canterbury Alps and the other in Cass Anticline of coastal Canterbury. Both the thrusts predate local folding attributed to the Kaikoura Orogeny, and in the Cass Anticline example, the displacement may be a Pleistocene syntaphral slide towards the contemporaneous Motunau submarine canyon.
