Stable oxygen isotopic analysis was performed on the UT-A stalagmite with annual microbanding from the Uchimagido Cave in Iwate Prefecture on the Pacific side of Northeast Japan. High-resolution anal...
In 1998, there were many volcanic earthquakes recorded at Iwate volcano, Japan. Although an eruption was anticipated, it never occurred. Fumarolic gases were sampled at the volcano on six occasions du...
Chemical and stable isotopic compositions (δD, δ18O, and δ34S) of non-volcanic hot spring waters around the Miocene Kofu granitic complex surrounding the Kofu basin in the South Fossa Magna region of...
The hydrogen and oxygen isotopic characteristics of precipitation in coastal areas of Japan were explained on the basis of a long period (23 years) observation of hydrogen and oxygen isotopic ratios ...
The atmospheric concentrations of nonsea-salt (nss) SO4 2– and trace elements (As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sb, Se, V, and Zn) were measured for aerosol samples collected concurrently at ten site...
Two piston cores (06GHSA P1 and 06GHSA P6) taken from the Ulleung Basin of the Japan Sea/East Sea were examined for the presence of an organic compound, diploptene (hopanoid 17α(H),21β(H)-hop-22(29)-...
Characteristics of δ2 H and δ18O in precipitation samples collected at 16- to 17-d intervals at three stations at the northern end of Honshu Island, Japan, were investigated. Rokkasho and Ajigasawa ...
Trace element and Sr–Nd–Pb isotopic compositions of basic schists in the Cretaceous Sanbagawa metamorphic belt, a typical regional metamorphic belt in the circum-Pacific orogeny, have been investigat...
Understanding the source and chemical characteristics of groundwater used for sake production is an important strategy for the quality management of sake brewing. Oxygen isotope ratios (δ18O) of 96 s...
Chemistry of surface waters from the Tateyama caldera known as a site of frequent landslides in northern central Japan was investigated to obtain the relationship between their geochemical characteri...
Increased emission of acidic pollutants on the Asian continent and long-distance transport of such pollutants have caused soil acidification in eastern Asia. In Japan, Hokuriku district experiences h...
Ore-forming fluid trapped in vein quartz as fluid inclusions from tungsten ore at the Takatori mine was extracted by a crush-leach technique. The trace metal content and isotopic composition (δ7Li an...
Geochemical mapping of 87Sr/86Sr ratios in Shikoku Island and the Kii Peninsula of Southwest Japan was performed using 233 samples of stream sediments (<180 μm). The spatial distribution of 87Sr/86Sr...
We present our April to December 2011 observations of 134Cs and 137Cs activities in surface water at Hasaki, a coastal station 180 km south of the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accid...
Sulfur isotopes in vein sulfides (galena, sphalerite, and pyrite) and pyrite sulfur derived from overprinting hydrothermal systems in the altered volcanic host rocks of the Toyoha–Muine area are dete...
