In a recent issue of Precambrian Research (vol. 170, pp. 73–87), Wang (2009) published a paper entitled ‘Tectonic evolution of the Hengshan–Wutai–Fuping complexes and its implication for the Trans-North China Orogen, in which he proposes that (1) the formation of arc-related igneous rocks in the Hengshan and Wutai Complexes formed by northwest-directed subduction, not by (south)east-directed subduction;...
Middle Miocene to Quaternary magmatism in Central Sulawesi (Indonesia) is characterised by radiogenic Sr and Pb isotopic signatures, and unradiogenic Nd isotopic ratios. Although the geochemistry of the samples is heterogeneous, all samples show a distinct subduction signature (negative anomalies for Nb and Ti, positive for K and Pb) in their trace element patterns. Mafic magmatism is represented...
