Hannes Mattsson

Hannes Mattsson is a Lecturer in Bedrock geology at Uppsala University's Department of Earth Sciences, specifically within the Mineralogy Petrology and Tectonics section. His research focuses on volcanic processes, particularly at the world's only active carbonatite volcano, Oldoinyo Lengai in Tanzania, and other volcanic systems across the East African Rift, Iceland, and Cape Verde.

Dr. Mattsson's research interests center on carbonatite magmatism and the complex relationship between silicate and carbonatite magmas. His work spans volcanic processes, magma genesis, and the petrological evolution of alkaline magmatic systems. He investigates fractional crystallization, magma mixing, mineral resorption processes, and the formation of volcanic landforms, with particular expertise in the unique natrocarbonatite system of Oldoinyo Lengai.

Analysis of his recent publications reveals a consistent research trajectory focused on understanding carbonatite genesis through multiple approaches: experimental petrology, detailed field studies of volcanic deposits, geochemical analyses, and rock magnetic investigations. His work demonstrates the importance of silicate-carbonatite immiscibility in magma evolution and how this process influences eruption styles and volcanic landform development. The research spans multiple continents, with significant contributions to understanding volcanic processes in the East African Rift, Iceland, Cape Verde, and Spain.

Dr. Mattsson has published extensively in high-impact journals including Lithos, Journal of Volcanology and Geothermal Research, Earth and Planetary Science Letters, and Bulletin of Volcanology. His work has been widely cited and referenced in policy documents, Wikipedia pages, and news outlets, demonstrating its significance to the geological community.

His research involves extensive fieldwork at active volcanic centers, laboratory analyses of volcanic products, and experimental studies of magma processes. Dr. Mattsson frequently collaborates with international research teams, contributing his expertise in petrology and volcanology to multi-disciplinary projects investigating volcanic hazards, magma evolution, and the geological evolution of rift systems.
