Shark Bay Stromatolites: Microfabrics and Reinterpretation of Origins

Reid, R Pamela; James, Noel P; Macintyre, I G; Dupraz, Christophe P; Burne, Robert

Description

Detailed analysis of microfabrics in Hamelin Pool stromatolites leads to reinterpretation of the origins of these structures. Previous studies have concluded that Shark Bay stromatolites form primarily as a result of sediment trapping and binding by microorganisms. Our results suggest that microbial precipitation of microcrystalline carbonate (micrite), as both framework and cement in these stromatolites, is also a fundamental, heretofore unrecognized, process in their formation.
