... the originally subducted material. Sediments and altered oceanic crust are enriched in boron and cesium relative to uncontaminated mantle products, and these elements are highly mobile during fluid-rock interaction. The combination of B-isotope systematics and Cs concentrations in lavas from the Halmahera arc...

... provides new insights into the Neogene history of Halmahera and the development of the present island arc. The Late Palaeogene and younger rocks rest unconformably on an ophiolitic Basement Complex which formed part of a Late Cretaceous–Early Tertiary fore-arc. After volcanic arc activity ceased...

... through the systems and the processes controlling these fluxes at different times during their history. Both arcs show increased evidence for sediment recycling as the collision progressed, but for contrasting reasons. In Halmahera this may represent an increased sediment flux through the arc front, while...

...R. HALL; M. G. AUDLEY-CHARLES; F. T. BANNER; S. HIDAYAT; S. L. TOBING Abstract Halmahera is a K-shaped island located at the junction of several major arc-trench systems of the western Pacific–eastern Indonesia region. Western Halmahera is an active volcanic arc above a zone of intense seismicity...

... of subduction hinges since about 10 Ma, and beneath the New Britain and Halmahera Arcs. There are several generally flat-lying deeper anomalies which are not related to present subduction. Beneath the Bird's Head and Arafura Sea is an anomaly which we interpret to be the result of north-dipping subduction...

... to the Halmahera Arc in Indonesia shows an excellent fit to observations if a broken-plate model of flexure is assumed. The model also gives an excellent fit to data from East Java, also in Indonesia, where it is possible to forward model gravity anomalies. In particular, the depth, location, and width...

In the case of both collision zones described above, the facing arc terranes may be differentiated on the basis of the (1) tectonic history and basement characteristics, (2) geochemistry, and (3) stratigraphic record. (1) Prior to the collision the Halmahera Arc-backarc underwent a period of shortening...

Our discussion of the stratigraphic record in Indonesian arcs is based mainly on studies carried out by the SE Asia Research Group in several different arcs over many years, especially in Java and Halmahera, but also in arcs of Sumatra, Sulawesi, and Borneo. These studies have...
