Rock-Powered Life NAI Team (2015-2019)

Theme 1: Systems undergoing low-temperature serpentinization as test-beds for determining habitability in water/rock systems.


Field sites: CROMO, Atlantis Massif and Oman 

Theme 2: Experimental constraints on pathways of water/rock interaction, in the presence and absence of biological processes.


Defining the pathways that control how energy is released from ultramafic rocks as they react with low-temperature fluids

Identifying and interpreting the process rates and ecology in systems undergoing water/rock reaction

Quantifying the geochemical and mineralogical progression of water/rock reactions in the presence and absence of biology

Characterizing microbial communities within rock-hosted ecosystems and evaluating their metabolic activities

Developing and testing predictive models of biological habitability during water/rock interaction

Re-examining the co-evolution and boundaries of physiochemical and biological systems.


The Rock-Powered Life NAI team asks:

How do the mechanisms of low temperature water/rock reactions control the

distribution, activity, and biochemistry of life in rock-hosted systems?
