Imaging Lithospheric Discontinuities Beneath the Northern East African Rift Using S‐to‐P Receiver Functions by Aude Lavayssière, Catherine Rychert, Nicholas Harmon, Derek Keir, James O. S. Hammond, J.‐Michael Kendall, Cécile Doubre, Sylvie Leroy

“…The northern East African Rift system is an ideal locale to study these processes as it exposes the transition from tectonically active continental rifting to incipient seafloor spreading. Here we use S‐to‐P receiver functions to image the lithospheric structure beneath the northernmost East African Rift system where it forms a triple junction between the Main Ethiopian rift, the Red Sea rift, and the Gulf of Aden rift. …”

A marine geophysical study of the Wilkes Land rifted continental margin, Antarctica by Close, D, David Close

Magma storage conditions beneath a peralkaline caldera in the Main Ethiopian Rift by Colby, DJ, Pyle, DM, Fontijn, K, Mather, TA, Nomade, S, Melaku, AA, Mengesha, MA, Yirgu, G

“…The MER is also an important site to gain insights into tectonic processes as it captures the transition from continental rifting (to the south) to incipient seafloor spreading (to the north). Peralkaline magmas account for around 90% of the volcanic products found in the MER. …”

The Pushtashan juvenile suprasubduction zone assemblage of Kurdistan (northeastern Iraq): A Cretaceous (Cenomanian) Neo-Tethys missing link by Sabah A. Ismail, Sarmad A. Ali, Allen P. Nutman, Vickie C. Bennett, Brain G. Jones

“…The compositional bimodality of the Pushtashan suprasubduction sequence suggests seafloor spreading during the initiation of subduction, with a lava stratigraphy from early-erupted MORB transitioning into calc-alkaline lavas and finally by 96 Ma intrusion of granodioritic and trondhjemitic bodies with juvenile crustal isotopic signatures. …”

Origin and evolution of Neoproterozoic metaophiolitic mantle rocks from the eastern Desert of Egypt: Implications for tectonic and metamorphic events in the Arabian-Nubian Shield by Shehata Ali, Mokhles Azer, Abdel-Aal Abdel-Karim

“…The proposed geodynamic model suggests that the oceanic lithosphere generated during the seafloor spreading of the Mozambique Ocean was emplaced in the upper plate of the intra-oceanic subduction zone, in which the formely depleted Neoproterozoic mantle of the Arabian-Nubian Shield experienced mature phases of hydrous melting, extreme depletion and enrichment. …”

Seismic structure, gravity anomalies, and flexure of the Amazon continental margin, NE Brazil by Watts, A, Rodger, M, Peirce, C, Greenroyd, C, Hobbs, R

“…We attribute the thin crust to either slow seafloor spreading or a limited magma supply during the initial rifting of South America and Africa in the Early Cretaceous. …”

Detachment Fault‐Hosted Subduction Re‐Initiation of the (Ultra)Slow‐Spreading Western Neo‐Tethys in the Jurassic by Tong Liu, Chuan‐Zhou Liu, Fu‐Yuan Wu, Gültekin Topuz, Bo Wan, Jia‐Min Wang, Guohui Chen

“…Based on field geological and geochemical evidence, we show that the Refahiye ophiolite in the İzmir–Ankara–Erzincan suture of northern Turkey has diagnostic characteristics indicative of (ultra)slow seafloor spreading. An (ultra)slow‐spreading nature also characterizes many Neo‐Tethyan ophiolites from the Alps to Southeast Asia, either at mid‐ocean ridges or in suprasubduction zones. …”

Eocene (46–44 Ma) Onset of Australia‐Pacific Plate Motion in the Southwest Pacific Inferred From Stratigraphy in New Caledonia and New Zealand by Edoardo Dallanave, Pierre Maurizot, Claudia Agnini, Rupert Sutherland, Christopher J. Hollis, Julien Collot, Gerald R. Dickens, Valerian Bachtadse, Dominic Strogen, Hugh E. G. Morgans

“…Synchronous sedimentary changes in the southwest Pacific occurred at the same time as onset of rapid seafloor spreading south of Australia and New Zealand. We infer that the underlying cause of stratigraphic change was inception of slip at a new configuration of the Australia‐Pacific plate boundary, which evolved into the Tonga‐Kermadec subduction system.…”

“…In some areas of the southern central graben, the crust may has broken up and entered the initial stage of seafloor spreading. The discontinuous HVZs in the lower crust in the back-arc region also indicate the migration of spreading centers in the back-arc region since the Cenozoic. …”

Geochemical cycling during subduction initiation: Evidence from serpentinized mantle wedge peridotite in the south Andaman ophiolite suite by Abhishek Saha, M. Santosh, Sohini Ganguly, C. Manikyamba, Jyotisankar Ray, Jagadish Dutta

“…These observations substantiate a subduction initiation process ensued by rapid slab roll-back with extension and seafloor spreading in an intraoceanic fore-arc regime. The boninitic composition of the serpentinized peridotites corroborate fluid and melt interaction with mantle manifested in terms of (i) hydration, metasomatism and serpentinization of depleted, MORB-type, sub-arc wedge mantle residual after repeated melt extraction; and (ii) refertilization of refractory mantle peridotite by boninitic melts derived at the initial stage of intraoceanic subduction. …”
