Actively-forming hydrothermal mineral deposits provide a source of energy for chemosynthesis and a substratum for colonization by adult and larval vent organisms. Since mineral deposition and organism growth can occur within similar time frames, their potential for interaction is substantial. The nature of this interaction is substantial. The nature of this interaction is the central theme of this paper. We review evidence for biological influences on deposit formation and destruction, and consider how the dynamics of sulfide chimney and mound growth may influence the distribution and composition of vent communities. Another theme that we develop concerns the mainly circumstantial nature of almost all evidence for biological-geological interaction. There exists very little experimental demonstration or solid statistical proof for links between biological or solid statistical proof for links between biological activity and mineral deposition processes at vents. This is not unusual for any new area of inquiry, particularly in a field that encompasses geological, chemical and biological data and observations. Indeed, these observations and ideas form the basis for suggestions for future experimental and field work. In order to encourage such experimentation, we discuss the types of evidence required to rigorously test the various hypothesis reviewed here.
