| Research Abstract |
I have investigated to develop a methodology to estimate formation age of natural gas hydrate. The remarkable findings are as follows. (1) Headspace analysis with gas chromatography mass spectrometry is one of the best methods to detect extremely low concentration of methanol in water. (2) Formaldehyde as well as methanol are main compounds formed by gamma-ray irradiation in methane hydrate. (3) Methanol and formaldehyde in pore water of deep-sea sediments gradually increase with depth.
