Abstract During the earliest Triassic microbial mats flourished in photic zones of marginal seas, generating widespread microbialites. It has been suggested that anoxic conditions shallow marine environments, linked to end‐Permian mass extinction, limited mat‐inhibiting metazoans allowing for this microbialite expansion. The presence a diverse suite proxies indicating oxygenated sea‐water (metazoan fossils, biomarkers and redox proxies) from successions have, however, challenged inference...
Abstract During IODP Expedition 310 (Tahiti Sea Level), drowned Pleistocene–Holocene barrier-reef terraces were drilled on the slope of volcanic island. The deglacial reef succession typically consists a coral framework encrusted by coralline algae and later microbialites; latter make up ≤80% rock volume. Lipid biomarkers analyzed in order to identify organisms involved reef-microbialite formation at Tahiti, as genesis microbialites conditions favoring their are not fully understood. Sterols...
The end-Permian mass extinction was the most severe biotic crisis in Earth’s history. In its direct aftermath, microbial communities were abundant on shallow-marine shelves around Tethys. They colonized space left vacant after dramatic decline of skeletal metazoans. presence sponges and sponge bioherms has largely gone unnoticed due to sponges’ size cryptic method preservation. addition dominated facies recently described South Armenia Northwestern Iran, we describe here sponge-microbial...
The main motivation for Integrated Ocean Drilling Program Expedition 310 to the Tahitian Archipelago was assumption that last deglacial sea‐level rise is precisely recorded in coral reefs of this far‐field site. succession typically consists framework subsequently encrusted by coralline algae and microbialites. high abundance microbialites uncommon shallow‐water reefs, environmental conditions favouring their development are still poorly understood.
Abstract Cold‐water coral (CWC) mounds are build‐ups comprised of coral‐dominated intervals alternating with a mixed carbonate‐siliciclastic matrix. At some locations, CWC influenced by methane seepage, but the impact on is poorly understood. To constrain potential mound growth, lipid biomarker investigations were combined mineralogical and petrographic analyses to investigate anaerobic oxidation (AOM) authigenic carbonate formation in sediment from seep‐affected Gulf Cadiz. The occurrence...
