The work was divided in two stages; the first was to evaluate the solubility capacity of thymine in ultrapure water and in artificial seawater as a function of temperature variation. The second stage consisted of thymine adsorption process in olivine. In seawater 4.0 Ga Na the solubility was lowest, and highest for 3.2 Ga in general averages. The great adsorption in 4.0 Ga Na seawater was observed.
