Notes on Vent Field Description: 
layered deposits of Fe silicates (nontronite) and Mn crusts; Baker et al. (1987): "Most of the basalt samples showed mineralogic alteration indicative of low- to moderate-temperature hydrothermal activity, including a single recovery (at 41°31'N) of massive hydrothermal nontronite and associated Fe and Mn oxides. The deposit was filled with worm tubes but contained no fauna."; near GR-9 in Baker et al. (1987)
Notes Relevant to Biology: 
Year and How Discovered (if active, visual confirmation is listed first): 
1984 deposits only
