| Research Abstract |
Study on geo-and bio-resource science and technology learnt from the processes in hyperalkaline springs at Oman was conducted by geologists, geochemists, biologists, engineers to understand geological condition and geo-scientific impact of hyperalkaline springs, adaptation mechanism of microorganisms and fish for hypealkaline condition, long-term stability of natural concrete and effective storage of CO_2 in geological strata. From the results of this study, the following points were cleared ; 1) petrology and structure of geology for production of hyperalkaline springs, 2) kinetics of carbonate formation at the hyperalkaline springs, 3) role of the aragonite and monohydro-calcite on anion migration in groundwater, 4) the highest δD value of hyperalkaline water, 5) existence of new micooganisms and their genes, 6) existence and adaptation to hyperalkaline water of freshwater fishes and frog, 7) strength and long term stability of natural concrete at Oman.
