The alkaline springs of the Voltri Massif, Liguria, Italy are beautiful natural springs created by active serpentinization in the subsurface. Like most serpentinite springs, they are not hot, but the springs are very high pH and, in some cases, are venting hydrogen and methane gas. The springs appear to have many similarities with the Tablelands springs.

 

Together with our collaborators, we have published the first metagenomic survey of archaeal and bacterial communities from the Voltri Massif springs in this paper:
