Spatial Distribution and Preservation of Carbon Isotope Biosignatures in Freshwater Microbialite Carbonate
Abstract
Understanding formation mechanisms of modern microbialites enables interpretation of biosignatures associated with fossilized stromatolites. Photosynthetic influences on carbonate precipitation are one proposed mechanism. Photosynthetic isotope biosignatures (13C) associated with freshwater microbialites in Pavilion Lake, British Columbia were widespread through the lake but less prevalent with increasing depth. Importantly, they were variably …
