Talk title: The evolution of life: Its preservation across ocean anoxic events (including major mass extinction events) from biomolecules and geomolecules to cellular remains
Speaker: Professor Kliti Grice, John Curtin Distinguished Professor in the Department of Chemistry and Director of the WA-Organic and Isotope Geochemistry team, Curtin University
Abstract: Oceanic anoxic events (OAEs) are sediments that contain high amounts of organic matter that were deposited under oxygen-depleted conditions and form an excellent archive for the reconstruction of ancient environments. Often OAEs coincide with mass extinction events, although many localised OAEs do not reflect global phenomena. Concretions are often preserved in sediments and can contain encapsulated fossil remains (e.g., bones, soft tissue). Concretions formed under highly reduced conditions allow for exceptional preservation of soft tissue and biomolecules (e.g., cholesterol. Concretions were formed over long geological time spans, but have never been studied in sufficient detail by organic –inorganic approaches that we have applied here. With access to concretions from several worldwide Lagerstätte locations (e.g., Lower Jurassic Posidonia Shale, NW Germany; The Devonian Gogo Formation, Western Australia) and the surrounding sedimentary shales (organic biomarkers, biomolecules and stable isotopes, inorganic geochemistry and morphology by imaging) reveal the extent of preservation of cholesterol and the entire diagenetic continuum as-well as exceptionally well preserved cells (unpublished) from sediments deposited under photic zone euxinic (PZE) conditions providing insights into the development and evolution of life (including highly important cellular remains).
About the speaker: Professor Kliti Grice is a John Curtin Distinguished Professor in the Department of Chemistry and Director of the WA-Organic and Isotope Geochemistry team at Curtin University. WA-OIGC play an integrated role in The Institute for Geoscience Research. Kliti has held two Australian Research Council (ARC) QEII fellowships and an ARC Discovery Outstanding Research Award (DORA) at Professorial level. Prior to joining Curtin University in 1998 Kliti was a research fellow at the Royal Netherlands Institute for Sea Research on the island of Texel, The Netherlands.
Kliti is a leading international authority on biomarker geochemistry and compound specific isotope analyses (CSIA) especially associated with mass extinction events. She is an organic geochemist who creatively combines geological information with data on biomarkers and their stable carbon, hydrogen and sulfur isotopic compositions to reconstruct details of microbial, fungal and floral inhabitants of ancient aquatic environments.
Professor Kliti Grice was awarded the GSA-WA Division’s 2016 Gibb Maitland Medal at the GSA-WA’s annual dinner and awards evening held in April.

2016 Gibb Maitland Medal
Call for Nominations - Now Closed
The Gibb Maitland Medal is awarded by the Western Australia Division of the Geological Society of Australia in order to recognize individuals who have made substantial contributions to geoscience in Western Australia. It is named for Andrew Gibb Maitland, Government Geologist from 1896 to 1926, who established the Geological Survey of Western Australia. The Medal is usually awarded each year and nominations are now sought for the 2016 Gibb Maitland medalist.
