The fossil tube walls are formed of an unusual quartz, barite, pyrite, and galena mineral assemblage, rather than only pyrite as in other vent fossils; this probably reflects the low-temperature, high-salinity vent chemistry at the time of preservation, as deduced from fluid inclusion analyses. The Madneuli vent fauna is one of three examples that occurred over a time span of ∼6 m.y. in an area of the Neotethyan Ocean that was as tectonically complex as the present-day west Pacific. The ancient and modern vent faunas appear to occur in a similar range of tectonic settings and bathymetry.
