Reconnaissance survey of the mineralogy and geochemistry of some New Zealand lake and nearshore sediments

Abstract
131 sediment samples representing 4 different environments (lakes, sounds, harbours, and fiords) in New Zealand have been studied and characteristic differences in chemical composition and mineralogy noted. These differences are related principally to the lithology of the sediments and the productivity of the lake waters. This study should provide a baseline for future surveys of lake sediment geochemistry in New Zealand.
