Microbiology of ancient and modern hydrothermal systems

摘要: Abstract Hydrothermal systems have prevailed throughout geological history on earth, and ancient Archaean hydrothermal deposits could provide clues to understanding earth's earliest biosphere. Modern support a plethora of microorganisms macroorganisms, good comparisons for paleontological interpretation systems. However, all the microfossils associated with reported date are filamentous, limited stable isotope analysis suggests that these were probably autotrophs. Therefore, morphology mode carbon metabolism attributes from modern valuable information interpreting record using morphological isotopic signatures.
