Abstract

Three samples of zircon from the Mangaroa Ash, an important marker bed in the late Pleistocene deposits of the Wellington area, have been dated by fission-track analysis. The average age of the 3 zircon samples is 380 000 years. Since this tephra fell, vertical uplift at Tinakori Hill on the northwest side of the Wellington Fault has been about 266 m, at a rate of about 69 cm per 1000 years; at the Whakatiki Terraces the minimum rate of uplift on the northwest side of this fault has been about 21 cm per 1000 years. -Authors
