Taphonomy of Organic Matter and Microbial Structures in Mid-Proterozoic and Paleoarchean Siliciclastic Succession

Learn about the preservation of ancient life traces in siliciclastic rocks through this scientific seminar presented by Dr. Brooke Johnson from the Université of Liège. Explore how understanding Earth's preservation mechanisms for organic matter and microbial structures can aid in the search for ancient life on Mars. Examine detailed research findings from the 1.4 Ga Greater McArthur Basin in northern Australia, focusing on the relationship between phyllosilicate composition and the preservation of biosignatures. Discover a new tapho-facies model that predicts optimal preservation locations within basins, and compare these findings with new data from the 3.22 Ga Moodies Group in South Africa's Barberton Greenstone Belt. Gain insights into how various depositional processes influence the preservation of ancient biological signatures across different geological time periods and environments.
