The lzu-Bonin-Mariana (IBM) arc system extends 2800km from near Tokyo, Japan to Guam
and is an outstanding example of an intraoceanic convergent margin (IOCM). Inputs from …

This paper presents a review of available petrological, geochonological and geochemical
data for late Mesozoic to Recent igneous rocks in the South China Sea (SCS) and adjacent …

The high field strength elements (HFSE) play a critical role in the interpretation of chemical
variation within subduction-related magmas by providing an assumed mantle-dominated …

The compositions of back-arc basin basalts (BABB) can usefully be viewed as products of
four factors:(1) the composition of inflowing mantle and its preconditioning during flow to the …

The Okinawa Trough is an incipient intracontinental back arc basin that has developed
behind the Ryukyu arc‐trench system. To explore its magmatic evolution and the nature of …

This paper develops methods for using the integrated study of Hf-Nd element and isotope
covariations to define the nature and provenance of the mantle and subduction inputs to …

It is unclear why the Pb, Nd, and Sr isotopic composition of the modern mid-ocean ridge
basalts (MORB) from the Indian Ocean is different from that of the North Atlantic and Pacific …

Quaternary volcanic rocks from the New Britain island arc display a wide range in chemical
compositions. The source of the lavas shares isotopic characteristics with Indian Ocean type …

The isotopic difference between modern Indian Ocean and Pacific or North Atlantic Ocean
ridge mantle (eg variably lower 206Pb/204Pb for a given εNd and 208Pb/204Pb) could …

New trace element and Sr, Nd, and Pb isotope data for lavas from the active Tonga–
Kermadec arc in the southwest Pacific, the volcano of Niua fo'ou in the back-arc Lau Basin …
