Concentrations of Re and Os and 187 Os/ 188 Os ratios were obtained on the modern sediment samples from two estuarine areas: the Tama River in Tokyo and the Yasaka River in Oita, Japan. The shallow ( depth 25 cm) intervals are 99.2–105.5 ppt Os tha

Strombolian-style volcanic activity has persisted for six years at the NW Rota-1 submarine volcano in the southern Mariana Arc, allowing direct observation and sampling of gas-rich fluids produced by actively degassing lavas, and permitting study of

After the phreatic eruption in 1982-83, volcanic activities at Kusatsu-Shirane volcano had been decreasing and reached a minimum in 1990, had turned to a temporal rise in activity up to 1994 and then decreased again at least up to 1997. During this l

A wide range of sediments formed in various sedimentary environments, including coals, carbargillites, shale and mudstones collected throughout China, have been studied by laboratory pyrolysis. The results show that the vitrinite reflectivity (Ro) va

It has been often observed that black mud recently formed and accumulated in slip planes that are closely associated with a progressing landslide in Japan. Mossbauer spectroscopy revealed that the composition of Fe species in the sliding mud is diffe

The vertical compaction of unconsolidated subsurface sediment was investigated at the Tama river estuary in Tokyo, Japan. The cores were taken by hand using polybutyrate tubes with different inner diameters, and core compaction ratios were measured i

Chemical states of Fe in the sliding mud and host rocks of landslide Kitayama and Tsuchikura were determined by 57Fe Mossbauer spectroscopy. The composition of Fe species in the sliding mud is different from that in the debris and bedrock. The slidin
