Proposed definition of the Kawakawa Tephra, the c. 20 000‐years‐ B.P. marker horizon in the New Zealand region

The Kawakawa Tephra is defined to include an upper Oruanui Breccia Member , a middle Scinde Island Ash Member , and a lower Aokautere Ash Member . It is recommended that the use of the name Oruanui Formation be discontinued. A type section is proposed together with a series of reference sections for the areas peripheral to the eruptive source.
