ASEG NSW - Talk by James Daniell (Fender Geophysics)
Mixed siliciclastic–carbonate margins receive significant amounts of both terrigenous siliciclastic material from rivers and carbonate material from biogenic sources. The Great Barrier Reef (GBR) is the largest mixed siliciclastic-carbonate margin on earth and detailed stratigraphic analysis is a key tool for understanding the evolution of this sedimentary system; however, the stratigraphy of the offshore central GBR is poorly understood due to its designation as a UNSECO World Heritage Site. This designation limited the acquisition of reflection seismic data over the GBR and has prevented detailed stratigraphic analysis of the reef and its margins. Geoscience Australia conducted limited seismic surveys over the GBR during the 1970-80s though much of this data has remained unprocessed and subsequently unpublished.
Sedimentary processes at the margin of the GBR are clearly diverse.
