(Bio-Isotopic) Message in a (Rock Record) Bottle: Who Wrote It, How Did It Get Here, and What Does It Tell Us? I Posters


Session ID#: 10304

Session Description:
Signals of microbial life in the rock record have expanded beyond physical fossil evidence to include molecular, elemental, and isotopic signatures. The methods used to derive these data have contributed to a better understanding as to the origination of key microbial metabolisms throughout Earth history (e.g. oxygenic photosynthesis, sulfate reduction). Indeed, there has been an explosion in the application of stable isotope proxies (e.g. C, S, Ca, Mg, Cr, Fe, etc.) used to investigate the rock record.  In this exciting geochemical ‘gold-rush’ it is critical that solid connections to modern microbial, physical and (geo)chemically ground-truthed constraints be established and maintained, particularly with regard to the production and preservation of bio-isotopic signatures.  In this session we invite contributors studying any period of Earth history, including modern natural and experimental analogues, using new or established methods for detecting microbial biosignals.
