In Pleistocene, the rift valley of Juan de Fuca area was characterized by complex sedimentation environment due to direct venting of fluids and the turbidite formation. Results of radiolarian analysis allowed us to determine the age and periodicity of the hydrothermal process activation: 300+ or -20, 200+ or -10, 100+ or -10, 41 K yr. Ecosystem analysis was ascertained that the periodicity may be related to the orbital fluctuation.
