(Table T3) Calcium carbonate mineralogy of ODP Leg 182 sites, Great Australian Bight@en

Carbonate mineralogy was determined on a total of 2845 samples from Sites 1126-1132 situated on the southern margin of the Australian continent. Five of these sites represent distal to proximal transects (Sites 1127-1131-1129 and 1132-1130), which penetrate principally Pleistocene-aged sediments. These sediments exhibit high concentrations of aragonite and high-Mg calcite (HMC) in shallow portions of the core, decreasing with depth. Dolomite was ubiquitous throughout these five cores and showed an inverse correlation in some instances with HMC. Sites 1126 and 1128 penetrated older strata and show lower concentrations of aragonite, HMC, and dolomite.
