High-Na dacite from the Jean Charcot Trough (Vanuatu), Southwest Pacific

Autor: Patrick Maillet, Tetsuro Urabe, Akihiko Fujinawa, Setsuya Nakada, Marie-Claire Monjaret

Publikováno v: Marine Geology. 116:197-213

Rifting that produced the Jean Charcot Trough (JCT) in the Vanuatu back-arc region commenced 2–3 Ma, leading to SiO 2 -bimodal magmatism in the northern half of the trough. Dacite with high Na 2 O (>6.0%) and low K 2 O ( Zr Rb >10 , Nb Rb >0.5 , Y

Petrology and geochemistry of the central North Fiji Basin spreading centre (Southwest Pacific) between 16°S and 22°S

Publikováno v: Marine Geology. 98:201-239

The North Fiji Basin (NFB) is a 12 m.y. old back-arc basin that has a complex multi-stage history. The presently active spreading system can be divided into four segments between 16°S and 22°S, which from north to south trend N160, N15 and N-S (the

Magmatism of the troughs behind the New Hebrides island arc (RV Jean Charcot SEAPSO 2 cruise): K-Ar geochronology and petrology

Autor: Patrick Maillet, Hervé Bellon, Marie-Claire Monjaret

Publikováno v: Journal of Volcanology and Geothermal Research. 46:265-280

The chronological, petrological and geochemical studies of lavas dredged from the New Hebrides back-arc troughs allow a new interpretation of the origin of these troughs. In every area, volcanism from the troughs precedes that of the adjacent islands

The geochemistry of basalts from the Wallis Islands, northern Melanesian Borderland: Evidence for a lithospheric origin for Samoan-type basaltic magmas?

Autor: Patrick Maillet, Jacques Dupont, Ian McDougall, R. C. Price

Publikováno v: Journal of Volcanology and Geothermal Research. 45:267-288

The Wallis Islands are located on the western extension of the Samoan seamount chain and are composed largely of basaltic flows and pyroclastics with ages that are less than 0.5 Ma. The youngest eruptives are tholeiitic in composition and are relativ

Backarc basins : tectonics and magmatism

Autor: Setsuya Nakada, Etienne Ruellan, Jean-Louis Joron, Martine Gérard, Joseph Cotten, R. C. Price, Patrick Maillet, Alain Person, Hervé Bellon

Publikováno v: Backarc Basins ISBN: 9781461357476

In the southwest Pacific, a discontinuous series of narrow and elongated troughs separates the New Hebrides island arc from the adjacent active marginal basin, the North Fiji Basin. This chapter reviews the structural, geophysical, geochronological,

Since 1987, Japanese and French geologists, geophysicists, and biologists have been studying the North Fiji Basin Ridge within the framework of a joint project named STARMER (Science and Technology Agency of Japan—IFREMER of France). This ridge was

Geodynamics of an arc-ridge junction: the case of the New Hebrides Arc/North Fiji Basin

Autor: Patrick Maillet, J.-Ph. Eissen, Michel Monzier, Rémy Louat

Publikováno v: Tectonophysics. 165:251-268

Detailed surveys (bathymetry, magnetism, seismicity and focal mechanism solutions) recorded on the junction between the southern New Hebrides Arc and the North Fiji Basin enlighten the geodynamic complexity of the area. The presently active c. N-S-or

Petrology of Matthew and Hunter volcanoes, South New Hebrides island arc (Southwest Pacific)

Autor: Michel Monzier, Patrick Maillet, Christian Lefevre

Matthew and Hunter, the two southernmost active volcanoes of the New Hebrides island arc (southwest Pacific) differ markedly from the other (mainly tholeitic) Quaternary volcanoes of this arc. Geodynamically related to the New Hebrides subduction zon
