Abstract :

Simpler compounds or elements like CO2, CH4, H2O (vapor), a small amount of NH3, and CO or N2-like materials with the continuous supply of thermal energy in hydrothermal vents can be possible to do structural modification to form stable compounds as deriving force. Alkaline hydrothermal vents are minerals-rich (Fe, Ni, S, and silica) and supplied with a temperature fluctuation of 400℃ to lower as we move away from it temperature decreases significantly, high pressure, active serpentinization fluids, reductive conditions and more important difference in concentration gradient are attributing to high interaction of materials at a single site. A combination of such events at one location can increase the chances of effective collisions, leading to possible combinations with different structural modifications. Plumes of Enceladus show the significant similarity of deep-sea hydrothermal vents condition with change in their ranges, even though the data shows 20 times more organic matter than expected in plumes. We are aimed to study the ⅀CO2 to synthesize C2+ hydrocarbons in deep- sea hydrothermal vents in presence of rich H2 and minerals with the chimney-like formation and the chemistry of three phases of water present on the planetary body with its possible application in biogenesis. Different research studies of analog sites and similar simulations at the laboratory favor complex material synthesis even though in an experiment the resultant shows imidazole presence. We are expected to formulate the study of potential changes in C/O/N summations with regards to the further fate of synthesized materials in deep-sea hydrothermal vents at Enceladus regarding earth even though variations are expected with natural changes in combinations of chemicals formed there. These conclusions can frame the basic information of life processes and their emergence with time and relative study of complexity increment.
