- Geochemical constraints on sources of metabolic energy for chemolithoautotrophy in ultramafic-hosted deep-sea hydrothermal systemsThomas M McCollom
CU Center for Astrobiology and Laboratory for Atmospheric and Space Physics, University of Colorado, Boulder, Colorado 80309 0392, USA
Astrobiology 7:933-50. 2007..The results indicate that ultramafic-hosted systems are capable of supplying about twice as much chemical energy as analogous deep-sea hydrothermal systems hosted in basaltic rocks...

Department of Geology, University of Toronto, Toronto, Ontario M5S 3B1, Canada
Nature 444:E18; discussion E18-9. 2006..which suggests that an alternative, abiotic origin for the methane is equally plausible. The conclusions of Ueno et al. about the timing of the onset of microbial methanogenesis might not therefore be justified...
