Late pleistocene tephrostratigraphy in the taupo district, new zealand

Abstract

Late Pleistocene rhyolitic tephras erupted in the period c. 20000–42000 years B.P. and preserved in the Taupo district have been mapped and described with reference to their field appearance and stratigraphic sequence. Five new formations of tephras erupted from the Taupo Volcanic Centre are defined; they are, from youngest to oldest: Poihipi, Okaia, Tihoi, Waihora, and Otake Tephra Formations. Their relationship is established with tephras of similar age erupted from the Okataina Volcanic Centre. © 1976 Taylor & Francis Group, LLC.
