[BAO01-17] Birth place of life on Hadean Earth: Geyser model
So where such molecules for life body are made on Hadean Earth. The most possible place for this process is geyser which locates below the ground. The reason why geyser is thought to be the most suitable site to synthesize building blocks for life body is (1) the ceiling of geyser located below the ground enable gases to be concentrated, such as CO, NH3, CH4, HCN, PO43- and so on. (2) Amino acid or peptide is possible to be synthesized as necessary material can be provided within cavity of geyser. (3) Periodicity is maintained due to the nature of geyser. (4) Heat source is secured due to the presence of uranium ore deposit which is the alternative heat source instead of solar energy.
