In this way much of the carbon in the fluids was locally precipitated as they moved, being unavailable for largescale transport and precipitation in veins. Thus, it may be difficult to find deep structures containing calcite that precipitated contemporaneously with microbial activity and likely to preserve evidence of metabolic processes. We show that duricrusts, biogenic lacustrine precipitates, hydrothermal and chemosynthetic precipitates, speleothems, travertines and evaporites all contain low-temperature fluid inclusions which represent surface/very-near-surface fluids.
