The Papua-Woodlark region exemplifies many plate tectonic processes, from active continental breakup to double plunging subduction zones. We present a synthesis of geological and geophysical data the interpret these characterize boundaries. A subducted slab shown underlie Trobriand forearc is associated with Papuan volcanic arc diapiric emplacement felsic gneissic domes in Woodlark rift previou...

e goal of this paper is to pose research questions that may help resolve controversies about the depositional setting of the ~ 5–6 Ma Bouse Formation and paleohydrology of the earliest Colorado River system. We also summarize and update a recent Geosphere paper (Crossey et a., 2015) that discusses the application of multiple geochemical tracers (87Sr/86Sr, [Sr], δ13C, δ18O) for understanding ca...
