Abstract:
The MNHN Microbialite Collection is intended to provide a community resource for the study and comparison of microbialites spread across geological time and from all over the globe. We determined the stable carbon and oxygen isotope compositions following the analytical procedure of Santrock et al. (1985) using a ThermoFisher Delta V Advantage isotope-ratio mass spectrometer (IRMS) at the isotopic analysis platform of the MNHN and a MAT253 instrument of the Pôle Spectrométrie Océan for the samples analyzed in Brest (PSO; Plouzané, France) both instruments were connected to a Kiel IV device. We determined the concentrations of selected major, trace, and rare earth elements, after a weak carbonate leach following the method of Rongemaille et al. (2011), using an ElementXR high-resolution inductively coupled plasma mass spectrometrer (HR-ICP-MS) of the PSO.
