Evaluating Serpentinization as a Source of Phosphite to Microbial Communities in Hydrothermal Vents

by Keith Cowing

Previous studies have documented the presence of phosphite, a reduced and highly soluble form of phosphorus, in serpentinites, which has led to the hypothesis that serpentinizing hydrothermal vents could have […]
