Summary
Thirty-eight samples collected from the southern Southern area North Island west coast, between Paekakariki and Otaki (i.e. N156509619 2.72 0.35 -0.34 1.46 Kapiti coast) were analysed by mechanical sieving to determine N156511622 2.00 1.02 -0.63 0.81 if chronologically distinct dunes exhibited characteristic N156509619 1.73 0.67 0.04 0.85 sedimentary parameters. Slight differences do appear to occur (Fig.1A) but the contrasts are of insufficient magnitude to be used N156509619 2.30 0.62 -0.40 0.86 alone as a diagnostic feature. The study indicates a strong N156510618 2.71 0.29 -0.23 1.24 environmental uniformity has been in existence for over 6000 (Fig. 10) N156512625 2.12 0.87 -0.53 0.67 years notwithstanding large changes in the quantity of N156512625 2.57 0.44 -0.40 1.24 sediments available for dune building and the input of N156513629 2.70 0.24 0.26 1.86 volcanic material.
