摘要

A theoretical simulation on the process by which the hydrogen isotope differentiation took place in the Earth during its early stage of evolution has been made by a model for the Earth's evolution. The result shows that, after having experienced a degassing process when the Earth became an open system from a close system, significant fractionation of the hydrogen isotope composition took place in the Earth's hydrosphere, crust and mantle. The closer to the Earth's core, the more negative the δD value of matter is. In other words, mantle-derived fluids are of extremely negative δD value. The initial δD value of the Earth was about -3‰ (relative SMOW) immediately after the Earth had been formed. The water content of the hydrosphere makes up about 96% of the total on the Earth. This has opened up a way of imminent Earthquake prediction by use of the hydrogen isotope changes that occur in hot springs along active deep faults.
