Occurrence of Magnesite–Dolomite Sediments in South Australia

Naturevolume 192page861 (1961) | Download Citation



IN November 1960 samples of precipitating sediment were taken from a lagoon of saline water near Salt Creek in the south-east province of South Australia. These were found to consist of magnesite and dolomite in about equal proportions. The salinity of the water was 3.2 per cent, and analysis showed that calcium constituted a much smaller proportion of the total salts than in normal sea-water. The proportion of magnesium was also lower. The pH was about 10.
