Abstract

An extensive terrace in the Waipaoa valley, eastern North Island, is underlain by at least 10 m of coarse, aggradational, river gravels. Tephra or tephric layers occurring in the lower cover beds were investigated at 5 sites using a combination of stratigraphy, mineralogy, and the major element composition of glass shards together with discriminant function analysis (DFA). Discussion of the results. The downcutting represents a major change in river dynamics and is most likely the response to climatic change and the resultant upper catchment landscape stability
