“…6). The extent of the gap of the Ontong Java Nui super plateau 22 and of the subducted Hikurangi Plateau portion (inferred by geochemistry, morphology and gravity; Fig. 5) suggests that we may have identified the missing piece of this super plateau.…”

“…This in turn suggests significant implications for the petrogenesis and eruptive behaviour of arc volcanoes, fluid-flow in their associated hydrothermal systems, and element transfer to the oceans. The Hikurangi Plateau is believed to have formed as part of Ontong Java Nui during the 'greater Ontong Java event' B120 Myr ago, one of the world's most extreme volcanic events, covering B1% of the Earth's surface 18,21,22 . As noted by Chandler et al 22 , a large part of the Hikurangi Plateau connecting its western and northern margin with the Ontong Java and Manihiki plateaus either does not exist or has already been subducted.…”

Subduction of the oceanic Hikurangi Plateau and its impact on the Kermadec arc

et al. 2014

Large igneous province subduction is a rare process on Earth. A modern example is the subduction of the oceanic Hikurangi Plateau beneath the southern Kermadec arc, offshore New Zealand. This segment of the arc has the largest total lava volume erupted and the highest volcano density of the entire Kermadec arc. Here we show that Kermadec arc lavas south of B32°S have elevated Pb and Sr and low Nd isotope ratios, which argues, together with increasing seafloor depth, forearc retreat and crustal thinning, for initial Hikurangi Plateau-Kermadec arc collision B250 km north of its present position. The combined data set indicates that a much larger portion of the Hikurangi Plateau (the missing Ontong Java Nui piece) than previously believed has already been subducted. Oblique plate convergence caused southward migration of the thickened and buoyant oceanic plateau crust, creating a buoyant 'Hikurangi' mélange beneath the Moho that interacts with ascending arc melts.

“…Here we use a hybrid plate motion frame and only the Columbia River Basalts overlie regions of faster than average velocities in the deep mantle. The Ontong Java, Manihiki and Hikurangi LIPs were modelled as fragments of a single LIP (the Ontong Java Nui) formed at around 123 Ma (Chandler et al 2012), and the Wallaby Plateau (originally 96 Myrs old) was assigned an age of 123 Ma after Olierook et al (2015). About 1700 kimberlites show a similar pattern (Fig.…”

Earth evolution and dynamics—a tribute to Kevin Burke

et al. 2016

Kevin Burke's original and thought-provoking contributions have been published steadily for the past sixty years, and more than a decade ago he set out to resolve how plate tectonics and mantle plumes interact by proposing a simple conceptual model, which we will refer to as "the Burkian Earth". On the Burkian Earth, mantle plumes take us from the deepest mantle to sub-lithospheric depths, where partial melting occurs, and to the surface, where hotspot lavas erupt today, and where large igneous provinces and kimberlites have erupted episodically in the past. The arrival of a plume head contributes to continental break-up and punctuates plate tectonics by creating and modifying plate boundaries. Conversely, plate tectonics makes an essential contribution to the mantle through subduction. Slabs restore mass to the lowermost mantle and are the triggering mechanism for plumes that rise from the margins of large-scale low shear-wave velocity structures in the lowermost mantle, that Kevin christened TUZO and JASON. Situated just above the core-mantle boundary beneath Africa and the Pacific, these are two stable and antipodal thermochemical piles, which Kevin reasons represent the immediate after-effect of the moon-forming event and the final magma ocean crystallization.

“…It has been proposed to be the centrepiece of Ontong Java Nui, a Super-LIP, because it was connected to the Ontong Java Plateau (OJP) in the west, the Hikurangi Plateau in the South and two subducted fragments in the East (Taylor 2006;Chandler et al 2012;Hochmuth et al 2015;Pietsch & UenzelmannNeben 2015;Hochmuth et al, in preparation). It was emplaced during three volcanic phases in the early Cretaceous: the initial formation phase (>125 Ma), followed by the expansion phase (∼125-116 Ma) and secondary volcanism (∼110-65 Ma; Pietsch & Uenzelmann-Neben 2015).…”
