Helium flux from a sedimentary basin.

چکیده
The tritium-3He ages of groundwaters collected from the Saijo Basin in Japan were measured. The ages vary between 11.7 and 16.3 years. The 4He flux of >3 x 10(4) atoms/cm2 s is calculated by the 4He concentrations and ages. In addition the helium flux of 8.3 x 10(5) atoms/cm2 s is calculated at the Higashi-Niigata gas field in Japan. The above two estimates are consistent with the continental helium flux reported in the literature, suggesting that helium flux on the Earth's crust is uniform.

Internal loading of phosphate in Lake Erie Central Basin.
After significant reductions in external phosphorus (P) loads, and subsequent water quality improvements in the early 1980s, the water quality of Lake Erie has declined considerably over the past decade. The frequency and magnitude of harmful algal blooms (primarily in the western basin) and the extent of hypoxic bottom waters in the central basin have increased. The decline in ecosystem health...
متن کاملInvestigating the Effect of Sedimentary Basin on Consolidation of Kerman Fine-Grained Soils
In this research, the effects of a sedimentary basin, environmental conditions, and the passage of time were investigated on consolidation processes and engineering characteristics of fine-grained soils in Kerman city. For this purpose, the natural consolidation curves of soil samples extracted from different locations of Kerman city were compared with the Kerman city intrinsic consolidation li...

During the recent field research on the Tirgan Formation in the west of Kopet-Dagh sedimentary basin, ammonite assemblages were obtained from the carbonate strata of this formation. This new finding is important for stratigraphical purpose. In this research, 3 genera belong to Heteroceras, Deshayesites and Cheloniceras? as well as one uncertain genus belongs to Turkmeniceras are determined. The...
متن کاملQuantifying He fluxes from the mantle using multi-tracer data assimilation
A global, coarse-resolution ocean model previously fitted to geostrophic shear estimates and to data of 10 hydrographic parameters and tracers has been used to simulate the 3He and 4He distributions resulting from the release of mantle helium from mid-ocean ridges. The model is in very good agreement with 14C and chlorofluorocarbon data and has realistic global ocean overturning strength as wel...
