“…The Foxton Dune Building Phase was estimated to be 4,000 to 2,000 years BP (Cowie, 1963). Shepherd (1987) suggests that the Foxton dunes began to accumulate at the end of the postglacial sea level rise 6,000-5,500 years BP, which is roughly the same as the inferred time the Te Onean dunes began to accumulate. Table 1 except NZ7293 and WK1538.…”

“…At two sections near the Manawatu River, 'Foxton' sand buries peat and trees with dates ranging from 2,270 to 1,595 years BP (Shepherd, 1987). The sand is interpreted by Shepherd (1987) as a final advance of Foxton dunes after dunes closer to the coast had become stable. If Shepherd's (1987) interpretation of his sections is correct, then my correlation is not supported.…”

“…The sand is interpreted by Shepherd (1987) as a final advance of Foxton dunes after dunes closer to the coast had become stable. If Shepherd's (1987) interpretation of his sections is correct, then my correlation is not supported. I suggest, however, that his 'Foxton' sand is derived from erosion of formerly stable dunes, similar to the erosion of Motuiti dunes during the Waitarere Dune Building Phase (Cowie, 1963), and that it represents the onset of a new unstable phase.…”

“…Bones of European-introduced animals (E) used to indicate a maximum age of 150 years. The end of the Foxton Dune Building Phase is dated by Shepherd (1987) as several hundred years after the end of the Te Onean Depositional Episode. At two sections near the Manawatu River, 'Foxton' sand buries peat and trees with dates ranging from 2,270 to 1,595 years BP (Shepherd, 1987).…”

Abstract:A recently developed approach to carbon isotope methodology (process recognition via isotope diagrams) is applied in a multidisciplinary study of precipitation-recharged aquifers of the lowlands-plains area of the Manawatu (south-west North Island). Urban and rural areas rely on groundwater from the upper levels of a deep basin sequence comprising marine and terrestrial sediments of Pleistocene age. Hydrochemical and isotopic ( 18 O, 3 H, 13 C and 14 C) data are merged with known details of geology and hydrogeology to reveal two separate confined aquifers within the depth range to 200 m. The shallower of these, below unconfined, locally recharged groundwater, is recharged on the foothills of the Ruahine Range to the north-east of the study area; flow direction is NE-SW. The deeper confined aquifer is recharged on the Tararua Range to the immediate east; flow direction essentially is transverse (SE-NW) to that in the shallower aquifer. Two processes are identified as dominant contributors to concentration and isotopic composition of dissolved inorganic carbon (DIC), namely addition of CO 2 from decay of organic materials and carbonate dissolution. Limitations of carbon isotope methods in determining residence times are illustrated by the data. Although the confined groundwater is essentially tritium-free, only a few samples showed conclusive evidence of significant ageing on the time-scale of 14 C.
