According to radiogenic isotope data, magma sources in the Banda Arc are the most heavily influenced by fluxes of subducted continental material among currently active oceanic island arcs. Hence, the results of this study suggest that high δ18O (>6.5‰) in arc lavas are difficult to reconcile with addition of subducted components to magma sources, but must reflect assimilation of arc crustal ...

Whole-rock 87Sr/86Sr and δ18O analyses of volcanic rocks and 3He/4He analyses of sulphides and sulphates from mineralized rocks on Wetar, Indonesia indicate a variable contribution of assimilated crustal material or sediment sourced from the subducted Australian craton to the south. These new data support the idea of progressive source contamination with precisely dated events showing that Wetar Island hosts the most extreme examples of crustal assimilation in the region. The increased continental ...

Initially cool sole rock was dynamo-thermally metamorphosed by heating from above by very hot, overriding oceanic lithosphere. Temperature equilibration between the sole and the Kaibobo lherzolitic complex (southwest Seram) took place at about 740°C and 4–5 kbar. Anatectic granitic magma formed in the sole and intruded in the ...

The oldest age in the literature for cordierite-bearing dacite, connected to this partial anatexis, sets the minimum age of the obduction event at 4.4 Ma. The obduction took place at the eastern end of the Banda Arc, near the NE margin of the Weber ...
