Origin, formation and environmental significance of sapropels in shallow Holocene coastal lakes of Southeastern Australia.

Title page, contents and abstract only. The complete thesis in print form is available from the University of Adelaide Library.The aims of this investigation on the Holocene carbonate successions of three shallow, ephemeral lakes from the Cooring coastal plain were: to determine the timing of the sapropel ’events’ in the three lakes; to determine the origin of the sapropelic organic matter and evaluate changes; to establish whether sapropel deposition in these shallow, coastal lakes primarily reflects increased organic matter delivery to the sediments during periods of enhanced terrestrial input and/or aquatic productivity, and; to relate sapropel deposition in these three lakes to both regional and global palaeoenvironment reconstructions. --p. 23-24.Thesis (Ph.D.) -- University of Adelaide, School of Earth and Environmental Sciences, 200
