Notes on Vent Field Description:

Tao et al. (2010): "This venting field lies on an N-S fissure belt in the axial uplift. Black smoker was video recorded while no hydrothermal fauna was found. According to the X-ray diffraction analysis, the sulfides collected by TV-Grab mainly consist of sphalerite and marcasite."; InterRidge e-news 2011: "Valentine Valley field is located at 14.41°W, 13.25°S and is about 4 km south of the Baily's Beads 2009 field"

Year and How Discovered (if active, visual confirmation is listed first):
