Journal ArticleDOI
The characteristics and chronology of the earliest Acheulean at Konso, Ethiopia
Yonas Beyene,Shigehiro Katoh,Giday WoldeGabriel,William K. Hart,Kozo Uto,Masafumi Sudo,Megumi Kondo,Masayuki Hyodo,Paul R. Renne,Paul R. Renne,Gen Suwa,Berhane Asfaw +11 more
TL;DR: A newly established chronometric calibration is provided for the Acheulean assemblages of the Konso Formation, southern Ethiopia, which span the time period ∼1.75 to <1.0 Ma, paralleling the emergence of Homo erectus-like hominid morphology.
Journal ArticleDOI
Gigantic SO2 emission from Miyakejima volcano, Japan, caused by caldera collapse
Kohei Kazahaya,Hiroshi Shinohara,Kozo Uto,Masanobu Odai,Yasuhiro Nakahori,Hirokazu Mori,Hideki Iino,Makoto Miyashita,Jun-ichi Hirabayashi +8 more
TL;DR: In the case of Miyakejima volcano in Japan, an extremely large amount of volcanic gas has been released since mid-August 2000 from the volcano after the formation of a summit caldera of 1.6 km diameter.
Journal ArticleDOI
Magma mingling as indicated by texture and Sr/Ba ratios of plagioclase phenocrysts from Unzen volcano, SW Japan
Brandon L. Browne,John C. Eichelberger,Lina C. Patino,Thomas A. Vogel,Kozo Uto,Hideo Hoshizumi +5 more
TL;DR: Clynne et al. as discussed by the authors found that plagioclase phenocrysts are engulfed during intrusion of basaltic to andesitic enclaves, which are composed of a densely packed network of micron-sized glass inclusions.
Journal ArticleDOI
Geology and eruptive history of Unzen volcano, Shimabara Peninsula, Kyushu, SW Japan
TL;DR: In the past 500 thousand years, Unzen volcano, an active composite volcano in the Southwest Japan Arc, has erupted lavas and pyroclastic materials of andesite to dacite composition and has developed a volcanotectonic graben as mentioned in this paper.
Journal ArticleDOI
Processes controlling along-arc isotopic variation of the southern Izu-Bonin arc
Osamu Ishizuka,Osamu Ishizuka,Rex N. Taylor,Makoto Yuasa,J Andy Milton,Robert W. Nesbitt,Kozo Uto,Izumi Sakamoto,Izumi Sakamoto +8 more
TL;DR: In this paper, the authors present new geochemical data including high-precision Pb isotopic measurements from the 700 km length of the Izu-Bonin arc, and link the along-arc characteristics with variations in the subducting Pacific crust.
