Dolomite is a Ca-Mg carbonate mineral with distinct socio-economic and paleoenvironmental significance, found in both marine and continental sediments and rocks. However, uncertainties remain regarding the conditions and the mechanisms of low-temperature dolomite formation. This thesis investigates the environmental and hydrological controls, and precipitation mechanisms of dolomite formation in low temperature groundwater systems in the Pilbara region of arid northwest Australia. Dolomite formed in shallow groundwater systems under saline and evaporitic conditions within a variety of landscape positions, during the Cenozoic. Clay minerals and microbial extracellular polymeric substances were found to provide nuclei for dolomite precipitation and growth.
