Dear microbialite community,

We cordially inform you that registration and abstract submission for the M-FED 25 (Microbialites – Formation, Evolution, Diagenesis) conference from September 30^th to October 3^rd 2025 in Hannover, Germany, is now open until the 15^th of April 2025!

We provide a scientific program with four key sessions covering the broad scientific research areas targeting microbialites and related topics:

1. Biofilms and their interaction with the environment

Keynote: Erika Kothe, University of Jena

2. Microbialites through deep time: unique archives for environmental reconstructions

Keynote: Johanna Marin-Carbonne, University of Lausanne

3. Microbialites in variable geologic settings: from continents to the deep sea

Keynote: Stanley Awramik, UC Santa Barbara

4. Mutual impact of microbialite mineralogy and environment

Keynote: Gernot Arp, University of Göttingen

Registration fees are 300 € (250 € for students) for in-person participation and 50 € for online participation. In-person fees include a field trip to the stromatolites of the UNESCO Geopark Heeseberg where Kalkowsky first coined the term “stromatolite”.

Please note that the maximum number of in-person participants is limited by the location safety guidelines to 100 (First come, first serve!).
