Ph.D Position in Geomicrobiology and Biogeochemistry
Are you an experienced researcher in the field of crustal tectonics with an emphasis on the interaction of small-scale to crustal scale deformation, fluid flow, and/or heat transfer? Do you want to make a contribution to our Earth Science department through excellence in research and teaching? Are you keen to use this knowledge to tackle societal issues related to sustainability and/or natural hazards? Please apply at Vrije Universiteit Amsterdam.
The PhD student will work in the field of geomicrobiology and biomineralization of carbonates, within the project Geobiological mechanisms controlling the formation of carbonate minerals at low temperatures. The overall aim is to investigate if and how microorganisms control the mineralogy and therefore, the geochemistry of carbonate minerals that grow at low temperature (< 50° C) to establish if these minerals can act as proxies of the paleo-conditions of formation. We will examine the hypersaline system in Laguna Fuente de Piedra (SW Spain), one of few places of present-day dolomite formation, and perform biotic and abiotic laboratory experiments that mimic natural environments (i.e., vary temperature, pH, salinity etc). The different metabolisms involved in carbonate biomineralization under oxic and anoxic conditions are expected to deliver characteristic nanotextural and geochemical signatures in both mineral and organic phases. Therefore, the characterization of dolomite in the hypersaline and evaporitic environment of Fuente de Piedra, coupled with laboratory experiments, will allow a quantitative interpretation of the processes that cause dolomite formation. Models developed from these data will be applied to examples of early Earth environments where unaltered carbonates are preserved to determine the palaeo-environment and possible role of life.
The project is highly interdisciplinary acting at the interfaces of sedimentology, geomicrobiology and geochemistry. The integration of field and laboratory studies with state-of-the-art analytical techniques will allow us to model the bio-physio-chemical controls of the geochemistry of carbonates formed with and without biological mediation. This project involves a multi-technique approach linking fieldwork, laboratory experimentation with the application of cutting-edge analytical and spectroscopic technique
