Trace element geochemistry of microbialites through time: Microbialites, rocks formed by microbes, incorporate trace elements that reflect their ambient environments and some aspects of the biological communities that formed them. Hence, these geochemical records provide important information on biological processes in ancient microbial communities while providing a window on the chemical evolution of Earth's environments through time.
Geochemical partitioning between limestone karst and speleothems: Speleothems, calcium carbonate structures formed in caves, provide important geochemical evidence of temperature and thus climate through time. However, information on rainfall trends is more difficult to acquire. Rare earth element geochemistry may provide the means to better understand hydrological processes during speleothem formation, thus providing additional constraints on palaeoclimate.
Early diagenesis in coral skeletons: Scleractinian coral skeletons are commonly analysed as geochemical archives of palaeoclimate data. However, geochemical data in corals can be disturbed by processes that affect the coral skeleton after death (i.e. diagenesis). Ongoing research suggests that diagenetic processes that operate in living corals already affect geochemical records to a significant degree.
