Deciphering magma storage and ascent processes of Taranaki, New Zealand, from the complexity of amphibole breakdown textures

Autor: David J. Prior, Robert B. Stewart, Gabor Kereszturi, Nessa G. D'Mello, Masako Usuki, Georg F. Zellmer, Yoshiyuki Iizuka, Marianne Negrini, Jonathan Procter

Publikováno v: Lithos. :106264

Lava flows that constitute the current edifice of Taranaki volcano, New Zealand, contain a complex crystal cargo including plagioclase, pyroxene, amphibole, oxides, and rarely olivine. Amphibole textures and mineral chemistry indicate that crystals a

Emplacement ages, geochemical and Sr–Nd–Hf isotopic characterization of Mesozoic to early Cenozoic granitoids of the Sikhote-Alin Orogenic Belt, Russian Far East: Crustal growth and regional tectonic evolution

Autor: Nikolai N. Kruk, V. Gonevchuk, Masako Usuki, Bor-ming Jahn, Galina Valui, Jeremy Tsung Jui Wu

Publikováno v: Journal of Asian Earth Sciences. 111:872-918

The Sikhote-Alin Range of the Russian Far East is an important accretionary orogen of the Western Pacific Orogenic Belt. In order to study the formation and tectonic evolution of the orogen, we performed zircon U–Pb dating, as well as geochemical a

Generation of Cenozoic granitoids in Hokkaido (Japan): Constraints from zircon geochronology, Sr-Nd-Hf isotopic and geochemical analyses, and implications for crustal growth

Autor: Sun-Lin Chung, Masako Usuki, Bor-ming Jahn, Tadashi Usuki

Publikováno v: American Journal of Science. 314:704-750

The island of Hokkaido is a young accretionary terrane, basically built with a Jurassic accretionary complex and Cretaceous arc in the west (= NE Japan arc terrane), a Cretaceous-Paleogene forearc basin and accretionary complex with the Hidaka metamo

Trace elemental and Sr-Nd-Hf isotopic compositions, and U-Pb ages for the Kitakami adakitic plutons: Insights into interactions with the early Cretaceous TRT triple junction offshore Japan

Autor: Soichi Osozawa, John Wakabayashi, Tadashi Usuki, Bor-ming Jahn, Masako Usuki

Publikováno v: Journal of Asian Earth Sciences. 184:103968

We conducted major, trace element, Sr-Nd-Hf isotopic, and U-Pb geochronologic analyses of early Cretaceous Kitakami granitic plutons, northeast Japan. We suggest that these plutons include rocks of adakitic affinity, which indicate partial melting of
