... 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...

... 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 in Sangihe...

...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.

... in the high seismicity area is essential to comprehend the tectonic study of Halmahera Island and its seismic hazard assessments. We utilized high‐resolution topography data with 0.6 arc‐sec resolution to evaluate a proposed fault line that was derived from a surface trace by Watkinson and Hall (2017...

... 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...

.... The Victoria Arc occupied a lower-plate setting during the collision and underwent subsidence during the collision, similar to the Australian active margin and Halmahera arcs in the southwest Pacific. The timing of the subsidence is constrained by three new ages of volcanic rocks in the Victoria Arc (457 ± 2...

The tectonic setting and seismicity map in northernmost Molucca denotes a subduction zone from Halmahera double collision in the western part. The Molluca sea plate moves around 5–6 cm/yr beneath Molluca plate and constructs a trench in the ocean and Halmahera volcanic arc on land (Gunawan et al., 2016). The inset map exhibits the 2022 earthquake distribution in the Tobelo region that occurred in an unidentified active fault. The top right corner inset shows the location of northernmost Molluca. The color version of this figure is available only in the electronic edition.

The Philippines, Sulawesi, and Halmahera consist wholly of upper Mesozoic(?) and Cenozoic island-arc subduction and magmatic complexes and lack old continental foundations. The scrambled fragments of the Philippines came from several arc systems, including 2 extending...
