Notes on Vent Field Description:
Tao et al. (2011): 2009 3rd leg of Chinese DY115-21 cruise with R/V Dayangyihao, "Two new hydrothermal fields were confirmed. One is named Precious Stone Mountain, which is the first hydrothermal field on the GM (Galapagos Microplate). The Precious Stone Mountain hydrothermal field (at 101.49 W, 1.22 N) is located at an off-axial seamount on the southern GM boundary, with a depth from 1450 to 1700m. Hydrothermal fluids emitting from the fissures and hydrothermal fauna were captured by deep-tow video. Few mineral clasts of pyrite and chalcopyrite were separated from one sediment sample, but no sulfide chimney was found yet."; Li et al. (2014): "Precious Stone field (PSF) on the Dietz Semount at the southern flank of the Galapagos triple junction"
Notes Relevant to Biology:
Tao el al. (2011): "Hydrothermal fauna such as alive mussels, crabs, shrimps, tubeworms, giant clams, as well as rock samples were collected by TV-Grab."
Year and How Discovered (if active, visual confirmation is listed first):
2009 deep-tow video and TV grab
