Determining main carbonate mineralogy, and the primary components of the non carbonate fraction, at three depths in core GC11, collected from the Capricorn Channel.
A gravity core (GC11) was collected from a depth of 502 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). Analysis of other parameters revealed the Last Glacial Maximum (LGM) sitting at a depth of ~30cm into the core. Three samples were collected for XRD analysis; at the sediment surface (GC11-0) representing interglacial sediment, at 260cm (GC11-260) also representing interglacial sediment, and from 160cm (GC11-160) - representing glacial sediment. XRD analysis shows that the majority of the interglacial sample (GC11-260) carbonate is made up of calcite. The glacial sample (GC11-160) is only 50% CaCO3 with the rest of the sample made up of quartz and clays.
