A geomorphological study of the South Wellesley Islands, southern Gulf of Carpentaria

摘要

This thesis details a geological history of the South Wellesley Islands, Southern Gulf of Carpentaria in Queensland, Australia over the mid- to late-Holocene. Field studies of the mixed bioclastic and siliciclastic coastal deposits on the South Wellesley Islands yielded significant data that was analysed in order to determine age constraints, the palaeo-depositional environment, rock composition and diagenetic history. The results of this research provide fundamental data for further work in producing a combined Holocene sea-level curve for the Southern Gulf of Carpentaria and the influence of sea-level change on the evolution of coastal environments in the tropical north of Australia.
