Lay Summary (German)

Lead
Die Geochemie der „clumped isotopes“ in Karbonaten befasst sich mit der Bestimmung der Häufigkeit der CO2-Moleküle, die aus den Isotopen 13C und je einem 16O und 18O bestehen. Ihre Häufigkeit ist temperaturabhängig und ermöglicht damit die Bestimmung der Bildungstemperatur von Karbonatmineralien. Anders als bei der herkömmlichen Temperaturbestimmungsmethode mittels d18O, ist der Einfluss der Isotopenzusammensetzung des Umgebungsfluides auf die „clumped isotopes“ vernachlässigbar.
Lay summary

Ziele und Inhalt: Aufbauend auf den Ergebnissen des Vorläuferprojekts sollen die Analysemethoden der 13C-18O Verbindungen in Karbonaten weiter verfeinert werden. Ziel ist es die Probengrösse auf weniger als 1 mg zu verkleinern und den Messfehler auf ±1°C zu reduzieren. Weiter soll ein Messverfahren für die 12C18O18O Häufigkeiten in Karbonaten entwickelt werden um dessen Auftreten in Abhängigkeit der Temperatur nach zu weisen. Damit diese beiden Ziele erreicht werden können, steht dem Labor die neuste Generation Massenspektrometer und dessen Peripheriegeräte zur Verfügung. In Zusammenarbeit mit dem Hersteller wird die Technik weiter verfeinert.

Die neuen Messverfahren werden ihre Anwendung einerseits in der Rekonstruktion der Klimaveränderung während des Juras finden. Dazu wird die Meerwassertemperatur anhand gut erhaltener Fossilien rekonstruiert. Andererseits werden Karbonatadern und – Zemente der mesozoischen Formationen des Genfer Becken auf ihre Versenkungs-, Zementations- und Dolomitisierungsgeschichte hin untersucht.

Der Kanton Genf unterstützt dieses Projekt, da man sich neuen Einblicke in die potentielle Nutzung der Sedimente für die Gewinnung von Geothermaler Energie erhofft.

Abstract

The clumped isotope thermometer in carbonates, is based on the measurement of the abundance of 13C-18O bonds in their mineral lattice. Unlike the classic oxygen isotope thermometer this method is independent of the composition of the water from which a mineral is formed. Therefore, it does not require assumptions of the composition of the water, which is commonly the largest source of uncertainty when reconstructing deep-time paleoclimates and diagenetic processes. With this project we will improve the methodology for the analysis 13C-18O bonds in carbonates (expressed the parameter ?47), in order to reduce sample sizes necessary to less than 1 mg of sample for a temperature estimate with an error smaller than ±1°C. A second goal is to develop the measurement protocols to determine the abundance of the isotopologue 12C18O18O in carbonates and to calibrate its temperature-dependence for the first time. Both the reduction in sample size and the measurement of the 12C18O18O isotopologue are possible thanks to the new ThermoFisher 253 Plus Mass spectrometer that was recently installed in our laboratory and which we are further developing in close collaboration with the manufacturer. The combination of a mass spectrometer with the new collector array with 1013 Ohm resistors for the rare isotopologues, and a new Kiel-IV preparation device is unique and will allow a much more efficient measurement workflow and the analysis of smaller samples. We will apply the new methodologies to samples that are not amenable to analysis with the current analytical systems. We will apply this new technology to two case studies: (A) Reconstruction of Jurassic climate change and oxygen isotope composition of seawater through the analysis of well-preserved fossils with a broad latitudinal range, and (B) Constraining the burial history and the cementation and dolomitisation history of Mesozoic formations in the Geneva basin by analyzing carbonate veins and cements. This second project will provide new temperature constraints to improve the modeling of the burial history of this sedimentary basin. In addition, it will help to better evaluate its potential for developing deep geothermal energy resources, which is the goal of a large ongoing project funded by the state of Geneva. Summarizing, the proposed project will be bring a significant improvement of the analytical techniques broadening the application of this method to new questions in earth sciences.
