Late quaternary deposits of the eastern shore of Lake Wairarapa, North Island, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Soil Science at Massey University
The lower Wairarapa Valley was an estuary as late as 6 500 years ago. Since then sediments from the Ruamahanga and Tauherenikau Rivers have deposited large loads of sediment into the area, prograding the eastern shore and changing the system from an estuary into lakes and rivers.
The aims of this study were to investigate the late Quaternary deposits and soils of the eastern shore of Lake Wairarapa, using the information gained to look at the way in which infilling has taken place.
The surface geology and soils of the study area were mapped. The mapping units were described and defined. Some chemical tests were carried out on selected soil samples.
The order and method of infilling of the deposits are discussed.
