Zusammenfassung der Projektergebnisse

Mit den Fördermitteln aus dem Koselleck-Projekt konnte eine neuartige Versuchsanlage zur Untersuchung der geometrischen Entwicklung von Reaktionsumsatz und Porenraumverteilung bei Wasser-Gestein-Reaktionen gebaut und eingesetzt werden. Das für den Betrieb der Experimentieranordnung benötigte Röntgenstrahl-Mikrotomographie (µ-CT) Gerät wurde beschafft und in vielfältigen Projekten eingesetzt. Das Gerät wurde nach Ablauf des Koselleck-Projekts ins MAPEX-Gerätezentrum der Universität Bremen überführt und wird dort für geound materialwissenschaftliche Untersuchungen eingesetzt. Die gebaute Durchflussanlage wird in aktuellen Studien zur Karbonatisierung von Basalt eingesetzt und weiterentwickelt. Aktuelle Kooperationen umfassen auch geobiologische Untersuchungen und die Kopplung der experimentellen Befunde mit numerischen Modellierungen. Die Projektmittel wurden außerdem eingesetzt, um Experimente in geschlossenen Autoklaven durchzuführen und haben es insgesamt dem Fachgebiet Petrologie an der Universität Bremen ermöglicht, experimentelle Arbeiten als Trittstein zwischen empirischen Studien submariner Hydrothermalsysteme und computergestützte Modellierungen zu etablieren.
