Microbial mats and thalassinid shrimp: Spatial and geochemical interactions in a modern intertidal environment

Sedimentology, EarlyView.
ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

Growth and reworking of freshwater microbially‐mediated carbonates in wind‐stressed lake margins (Lago Sarmiento, Southern Patagonia)

Sedimentology, EarlyView.
ABSTRACT Understanding the biotic and abiotic influences on the deposition and diagenesis of recent microbial carbonates is crucial for addressing the environmental and ecological significance of ancient organosedimentary structures. This study investigates these factors and their expression in the microstructure of Holocene tufa thrombolites from a ...

Evolution Model for the Paleoproterozoic Talvivaara Mudstone‐Hosted Ni‐Zn‐Cu‐Co Deposit in Fennoscandia

Terra Nova, EarlyView.
ABSTRACT The Paleoproterozoic Talvivaara mudstone is a very large sulfidic Ni‐Co deposit that records enhanced organic matter accumulation during the global Shunga Event. Here, rock geochemistry and microscale S and Fe isotope composition of in situ pyrrhotites and pyrites are studied in well‐characterised, well‐preserved drill core samples.
