My Scientific Interests

of Dr. Setsuya Nakada

Present Research Themes:

• Geology and petrology of the 1991-1995 eruption at Unzen--especially degassing and crystallization of magma during ascent: Edited special issue of this eruption with John Eichelberger and Hiroshi Shimizu in Journal of Volcanology and Geothermal Research (Elsevier) (v.89, 1999)
• Origin of phenocrysts and magma process in magma reservoir
• Petrochemical evolution of the Izu-Oshima Volcano (using core sample from the drilling of 1 km long within the caldera)
• Chronological and geological researches of Usu and Miyakejima eruptions in 2000.
  
• Geological and petrological study on Unzen Volcano with scientific drilling (2003-2004): Edited a special issue of the scientific results in Jour. Volcanology and Geothermal Research (Elsevier) (in press, 2008)
• Petrological study of earliest stage of Mount Fuji using drilling cores.
  
• Geological and petrological researches of the 2004 eruption at Asama volcano and eruption at Anatahan (Northern Marianas) since mid-2003.
• Comparative petrological study of Asama and Galeras (Colombia) volcanoes.
  

Research Records:

• Geology and petrology of the Osuzuyama acid rocks (one of the Miocene felsic extrusive volcanic provinces in Kyushu-a stratified zoned magma chamber; Journal of Petrology in 1983)
• Petrochemical study on the Miocene felsic igneous rocks in the Outer Zone of SW Japan (regional variation of magmatic nature and the petrogenesis in a tectonic regime, co-working with M. Takahashi, Y. Okamoto, and S. Hirahara)
• Petrochemical study of the Cenozoic volcanic rocks in central and northern Kyushu (evolution of mantle wedge during subduction, co-working with H. Kamata; Bulletin of Volcanology in 1991)
• Petrology of the central Andes dacites (petrogenesis of sphene-bearing highly oxidized magma; American Mineralogist in 1991
• Geology and petrology of Unzen Volcano (a history of Unzen Volcano and petrogenesis of the Unzen magma, co-working with M. Tanaka)
• Petrology of Vanuatu back-arc basin volcanic rocks (origin of high-Na dacites, co-working with Japan-French marine-science group; Marine Geology, 1994)
• Petrology of pre-Mazama rhyodacite (origin of phenocrysts, co-working with C. Bacon and A. Gartner; Journal of Petrology)
• Geological and Petrological study of the 1990-1995 eruption at Unzen (chronology and observation of the eruption, co-working with H.Shimizu, Y. Motomura, T. Fujii, etc.; Journal of Volcanology and Geothermal Research, 1993; 1999 etc.)
• Chronological and geological studies of Usu and Miyakejima eruptions in 2000 (Usu special issue from Bulletin of ERI, 2001 in Jpn; Miyakejima issue was edited as the first speical issue from Bulletin of Volcanology (Springer) with Tim Druitt, v. 67-3, 2005)
• Geological study of the 2003-2004 eruption at Anatahan volcano, Northern Mariana Islands (Jour. Volcanol. Geotherm. Res., 2005)
• Geological study of Asama eruption in 2004 with Mitsuhiro Yoshimoto and others (Bull. Volcanol. Soc, Jpn, 2005)
  
• Petrological study of the scientific drilling at Unzen, working as the sceince leader of project (Scientific Drilling, 2005, Jour. Volcanol. Geotherm. Res., 2008 etc)
