...Magali ZBINDEN; Isabelle MARTINEZ; Françoise GUYOT; Marie-Anne CAMBON-BONAVITA; Françoise GAILL Abstract Nanocrystalline zinc-iron sulphide minerals were found within tubes of Alvinella pompejana , collected at 9°N on the East Pacific Rise, in a preliminary study carried out by conventional...

..., possibly siboglinids (vestimentiferans). This is because the closest analog at modern vent sites in terms of size and shape are the tubes of some siboglinids (particularly Riftia ), chaetopterids, and the larger alvinellids (e.g., Alvinella ), which can become replaced by sulfide minerals ( Haymon et al...

...); 2) are relatively, or completely sessile; and 3) have carbonate shells or chitin-rich tubes. These fossils are tubes of the polychaete Alvinella spp. from the East Pacific Rise ( Haymon et al., 1984 ; Haymon and Koski, 1985 ; Maginn et al., 2002 ), Ridgeia piscesae tubes from the Juan de Fuca...

The worms live on active sulfide chimney walls, where they are exposed to steep thermal and chemical gradients and intense mineral precipitation...

... similar symbioses. However, the speciation of iron can strongly affect the abundance and availability of the energy sources available in hydrothermal fluids. For example, in Alvinella pompejana tube worms on the East Pacific Rise, Fe(II) has been shown to be critical for forming FeS (aq) clusters...

This organization would be somewhat analogous to the distribution of biogenic Fe/Zn-S spheroids within inner organic layers of the hydrothermal vent tubeworm Alvinella pompejana observed by Zbinden et al. (2001) , except that the SRB biofilm in the Piquette mine appears to be growing...
