Geochemical and Geochronological Constraints on the Origin and Evolution of Rocks in the Active Woodlark Rift of Papua New Guinea
… a better understanding of rocks in the active Woodlark Rift, situated in Papua New Guinea's southernmost reaches. In this region, rifting and lithospheric rupture is occurring within a former subduction complex where there is a history of continental subduction and (U)HP metamorphism. The …

Temporal and petrological constraints of ultrahigh-pressure metamorphism and exhumation of crustal material from mantle depths to Earth's surface: Insights from a large and small ultrahigh-pressure terrane
… is actively exhuming, in this case within the Woodlark Rift. To better understand the pressure-temperature-time-deformation path taken by this young UHP terrane, a suite of fresh to nearly-completely retrogressed eclogites were sampled from Oiatabu, Mailolo, and Goodenough Domes for …

Multi-timescale mechanics of an active low-angle normal fault
Detachment faults dipping < 30° commonly accrue 10’s of kms of offset and accommodate a large portion of crustal extension in moderately-to-highly extended regions. Slip on these high-offset low-angle normal faults remains perplexing due to their apparent misorientation relative to Andersonian …
