Resumo |
We have measured the 3He/4He and 20Ne/4He ratios of gases dissolved in the pore water in sediments at two sites in the Nankai Trough (Site 583) and the Japan Trench (Site 584). The 3He/4He and 20Ne/4He ratios vary from 0.215 * 10**-6 to 1.23 * 10**-6 and from 50 * 10**-3 to 2700 * 10**-3, respectively. These values can be explained by mixing two components, one from the atmosphere and one with a 3He/4He ratio of (0.2 to 0.3) * 10**-6. The latter component may be derived from the ocean crust near the subduction zone. |
