A microbial ecosystem in the 3.48 Ga Dresser Formation, Pilbara, Australia

Dr Nora Noffke – Old Dominion University

The Archean Pilbara Block in Australia is known to host some of the oldest fossils in Earth history. This presentation focuses on microbially induced sedimentary structures (MISS) in clastic sabkha deposits of the Dresser Formation. Similarities of modern and fossil MISS suggest that already in the early Archean time complex microbial ecosystems existed.
