Geochemical development of the late Cenozoic arc volcanism in Northland and the Coromandel and implications for geochemical exploration in the Hauraki goldfield

Abstract

Late Cenozoic subduction-related volcanism in northern New Zealand left a record in Northland, the Coromandel and, from 2 Ma, in the central North Island. Over 90% of the volcanic succession formed prior to the intensely studied central North Island volcanism. This study documents geochemical and isotopic characteristics of volcanic rocks of the Northland Arc and the Coromandel Volcanic Zone (CVZ). Rocks are basaltic, andesitic, dacitic to rhyolitic, with subordinate trachybasalts to trachydacites
